#8068: A crash bring up the app_server in gdb when changing the screen

Comment (by mmlr):
I've built a small script that gets the app_server reliably crashing after
a couple of seconds when running normally:
{{{
while true
do
screenmode -q 1280 1024
screenmode -q 1024 768
done
}}}
Which will cause continuous mode switches until the crash happens.
Using that I've confirmed that this only happens when both CPUs (it's a
dual core machine) are active. Disabling one core prevents the crash from
happening. So I'd suspect that the vm86 stuff needs to run on the same CPU
that it was set up on and causes side effects leading to the crash
otherwise.
