immediately reproduce the problem again as many times as I want by
the test scenario.
However, I don't understand how wine can block the X server from doing
even cursor updates. It might be a scheduler bug, of course. The
a bigger pipe buffer does is end up changing scheduling behaviour.
(On the other hand, I would not be surprised if Wine does something
makes X pause, like use DGA or whatever and tells X not to update the
screen, including cursors).
If the application captured the mouse/keyboard and did not pass them
X for some period of time, then X would appear to not respond to VT-
requests, because those keys go through the same handler loop
the way your X is configured, of course).
I've had incidents where a user forkbomb was able to hang X (and
the console) while our SCHED_RR rate-limited SSH daemon was running fine
and able to successfully kill the process.
