[Red5] Unable to delete stream after replay.

[Simon Li]

Hi list!

I write a simple AS3/Red5 project that capture/replay video from webcam.
However, the call to remove the temp file often fails if it has been 
replayed.
I think it might be a cache issue. But I don't know how to clean the cache 
on server side.
Any suggestion?
Thanks for your attention.

Note for code snippets
==============
I remove some "irrelevant" code to keep it clear.
In attached code, doDiscardStream won't remove the file on server if 
doReplayStream has been called.
