This patch won't be going in.  The purpose of the lock is to ensure
speed changes only occur when the lock is not held by the decoder
thread and this change defeats that.

The proper fix is to have NVP::GetFrame return early when it can't get
a free buffer after a small amount of time.  Be sure to update the
ivtv decoder for the skipping frames case because it works
differently.  Also leave some kind of check to inform the user when
the buffer queue really does get stuck.
