that looks like an extremely usefull option for developpers, I don't
even recall how often I needed a remote login to debug programs that
use grabs :)

For the average user this is still a bit difficult I am afraid.

client didn't go away in my case so it is not an X bug. An strace
displayed some SIGALRM in qemu and nothing else as far as I could see.
After killing qemu the X server was fine again.

Now, excuse for the completely offtopic Q: Once every year or so
my Xemacs looses sync with the Xserver.. usually there is some
message suggesting xlib lost some reply or got an unexpected one.
Is there any way to revive the app in such a case?
