[Live-devel] Busy waiting on file sources

No, your approach is OK.  A fix, probably similar to this, will 
appear in the next release of the code.  Thanks for the note.

Out of curiosity, what kind of data are you streaming when you 
encounter this situation?  (The problem that you noted will occur 
only for some media types; for others, "doGetNextFrame()" won't end 
up getting called until the downstream recipient is actually ready to 
get/handle new data.)
