ctrl-c sends a SIGINT (and not SIGSTOP like I said earlier ... my bad
and thanks for ahuemer for pointing it out on IRC :p).

This means that if the GR process is in a system call at that time,
that syscall will be interrupted and return -EINTR and my guess is
someone, somewhere isn't dealing with that properly.
