Ha, they'll be even more upset when they discover that they can't (easily)
interrupt;). Suspending, then kill -9 on Unix is the only way I succeeded.

This is a boring problem. If the server stops responding at all, we just
set a flag and never reach a cancelation check. I don't know how to fix
this. We want to run cleanup, but we don't want interrupted system calls
to be restarted.
