When Melanie added the web fetch inventory throttle to core, she made the long poll requests (EQs) effectively be handled on an active loop. All those requests, if they existed, were being constantly dequeued, checked for events (which most often they didn't have), and requeued again. This was an active loop thread on a 100ms cycle!
This fixes the issue. Now the inventory requests, if they aren't ready to be served, are placed directly back in the queue, but the long poll requests aren't placed there until there are events ready to be sent or timeout has been reached.
This puts the LongPollServiceWatcherThread back to 1sec cycle, as it was before.

block will trigger a Monitor.Wait() to exit, so avoid some locks that don't actually affect the state of the internal queues in the BlockingQueue class.""
This reverts commit 21a09ad3ad42b24bce4fc04c6bcd6f7d9a80af08.
After more analysis and discussion, it is apparant that the Count(), Contains() and GetQueueArray() cannot be made thread-safe anyway without external locking
And this change appears to have a positive impact on performance.
I still believe that Monitor.Exit() will not release any thread for Monitor.Wait(), as per http://msdn.microsoft.com/en-gb/library/vstudio/system.threading.monitor.exit%28v=vs.100%29.aspx
so this should in theory make no difference, though mono implementation issues could possibly be coming into play.

This reverts commit 42e2a0d66eaa7e322bce817e9e2cc9a288de167b
Reverting because unfortunately this introduces race conditions because Contains(), Count() and GetQueueArray() may now end up returning the wrong result if another thread performs a simultaneous update on m_queue.
Code such as PollServiceRequestManager.Stop() relies on the count being correct otherwise a request may be lost.
Also, though some of the internal queue methods do not affect state, they are not thread-safe and could return the wrong result generating the same problem
lock() generates Monitor.Enter() and Monitor.Exit() under the covers. Monitor.Exit() does not cause Monitor.Wait() to exist, only Pulse() and PulseAll() will do this
Reverted with agreement.

Fixing LLClientView memory leak by disposing of all timers utilized
in LLClientView as they contain references to the callback method.
This required the use of the Terminate and Close infrastructure that
was already in place but was not being utilized.

* This patch is highly experimental and may cause clients to not be able to connect, if this is the case, it will be rolled back in approximately 5 minutes.

resending, timeouts, packet discarding. Add notification event for
packet discarding. Add priority scheduling for packet queues.
Add outgoing duplicate detection facility. Correct packet sequencing.
Make provisions for automatic server side throttle adjustments (comes
in next installment)

* Added new generic "Location" class to handle 2D integer locations. Going to use it to replace all RegionHandle and X,Y coordinate references throughout the entire project. You have been warned.

confirmed that this fixes the issue, however functional
correctness of BlockingQueue requires that these locks be
put into place anyway.

support for region move/split/merge. See ThirdParty/3Di/README.txt. Unless the new modules are used there should be no noticeable changes when running OpenSim.

Just want to try this out on windows quickly.

* The BlockingQueue exposes Contains so we can make sure we don't add a TextureSender to the queue if there's already one present
* introduced some TryGetValue and various code convention stuff
|

* shortened references
* Removed redundant 'this'
* Normalized EOF

Have flattened the OpenSim.Framework project/namespace. The problem is that the namespace is still wrong as its "OpenSim.Framework" while the directory is "OpenSim\Framework\General" , so we need to decide if we change the directory or correct the namespace.
Note this has lead to a big flat project, but I think a lot of the files we most likely don't even use any longer. And others belong in other projects/namespaces anyway.
