'already dispatched' message completely temporarily
* I believe that if the Linden client has not started to receive a texture after 15 seconds, it re-requests it.
* My hypothesis is that the texture packets are often still in the texture queue (esp. if the client has just cleared its cache), so another load of packets get added...
* If this is the cause, resolution is going to be rather complicated.

requests for missing textures
* Also minor logic change so that we actually do retry missing texture requests (we weren't before)

when we start dropping requests
|
|
n=5), we now drop the subsequent requests
* This may improve region memory usage
* This is a short-term response to a problem whereby some clients keep requesting the same texture even after we've sent it
* This treats the symptom rather than the cause.
* n can be adjusted by changing the constant at the top of UserTextureDownloadService if necessary

already have received
* The warning will be
[USER TEXTURE DOWNLOAD SERVICE]: Received {0} requests for already dispatched texture {1} from client {2}
This is to see whether the texture packet queue memory leak is caused by clients continually re-requesting textures they should already have

AssetCache for it if we know it's missing.

textures (probably for some good reason) by dropping all subsequent requests after the first reply.
* Print out a console message every 20 tries rather than every single one.
* This weakens the problem but does not eliminate it
|
|
* Reduce 'asset not found' console debug spam
|
|
an image
* This might stop some client's constant requests for unfound textures, which is a candidate for the memory leak
* If a texture is not found then the "Image not found" texture will now be displayed clientside
* If it works, this should resolve mantis 676
* Non texture image requests do not receive this packet yet
* This will require a prebuild

* Moved Flush into Close since it's always done in that order.
* Minor renamings
* Reversed if for clarity

data from the asset server
* This should stop the constant increase in the download requests statistics
* If you see stat numbers for download requests which are far from what you'd expect, please report
|
|
|
|
* This fixes some of the 'runaway downloads' problem but not all of it
* Also fix up logging messages so texture requests are reported as such rather than as assets
|
|
* The reason why pending downloads tick ever upwards is because missing assets are never signalled to the TextureSender
* Rectifying this is not straightfoward, but this will constitute the next patch.
* This does not explain the memory leak.

memory
* However, I'm no longer sure they were even a big contributory factor (to this particular leak, there are other causes of other leaks). I need better measurement techniques
* Removed most of my debugging gawp

Just want to try this out on windows quickly.
