|Subject: [PATCH] Closed two major memory leaks for scripted objects
|
|Two major memory leaks for the scripted objects were fixed
|- One leak had to do with remoting acrossing app domains.  When a script and
|  its controlling agent communicate across an application boundary, it calls
|  functions on a stub proxy object that then invokes the remote method on
|  the object in the other app domain. These stub objects (two for each script)
|  were setup to have infinate lifetimes and were never being garbage collected.
|- The second leak was the result of adding a scene object part instance method
|  to a scene event and never removing it.  This cause the event's delegate list
|  to maintain a link to that object which is then never freed as the scene event
|  object is never destroyed.

Patch applied, please direct feedback to me. Possible issue: Longtime idle
scripts like vendors may fail.
