[Mono-list] Winfessor Patches for Jabber

Hi guys,

Just a quick pop-in, the queue threshold was there to tell the thread
pool to create new worker threads to handle the load. The thread pool
should have at least one thread from the startup to handle request and
therefore it should always handle the queued items directly. Your patch
sets that value to 0, forcing the thread pool to create new threads
directly and more or less making the thread pool non dynamic, if we
should increase the speed the thread pool spans new thread the parameter
should at least be set to 1.

I will try to get an hour in the weekend to verify the threadpool
functionality (it's me that made it from the start ;-).
