Strange stalls in asynchronous processing

[Piet van Oostrum]

Today I noticed strange stalls when using asynchronous processes, e.g. a
compilation in a comint window, or a long grep. Very regularly the process
output stalls and only continu when I give some input to emacs. this can be
a keyboar input or a mouse click, even changing focus or moving a window
will help. I haven't noticed this before, but usually I continue typing
while the background process is running. 

This is on the 22.0.93 pretest, compiled from the tarball on Mac OS X 10.4
(Tiger). Has anyone experienced the same behaviour or is this a known problem?
