[issue37389] Memory Leak - ThreadingUDPServer

[Daniel W Forsyth]

New submission from Daniel W Forsyth <danf at dataforge.on.ca>:

After putting a basic ThreadingUDPServer under load (500 messages per/second)  I noticed that after a night it was consuming a lot of RAM given it does nothing with the data.

On inception, I noticed the _thread count inside the server was growing forever even though the sub-threads are done.

Setup a basic ThreadingUDPSever with handler that does nothing and check the request_queue_size, it seems to grow without limit.
