Perhaps I should explain a bit more...
If you stall the main E-UAE thread (and thus the generation of audio data),
then you stall audio output. Thus, if E-UAE has to wait while other apps talk
to the windowing system, audio output will stall.
However, if you make the communication between E-UAE and the windowing system
asynchronous, then the primary reason for stalling the main E-UAE thread is
removed. Okay, the graphical output will still be stalled - but it's much
better that only graphical output be stalled rather than also CPU emulation
and audio output.

Rich
