Of course the other application gets control via getnextevent to have a
slice of time for processing. If the sound buffer doesn't have sufficient
bytes in it then you'll get a pause or the replay? until control returns to
squeak and you get more bytes into the sound manager. Mind this is
speculation on my part but it would be interesting to know how many msecs
are buffered versus how long that getnext/waitnextevent takes. Say for
example what if that Endora app sucks up 750ms once and awhile?

BTW I was unable to create the condition on my PB500
