From: Richard Henderson
linux-user blocks all signals while attempting to handle guest
signals (e.g. ABRT), which means that the default TERM sent by timeout
has no effect -- KILL instead.
When a guest aborts (possible nios2 guest bug), sending SIGABRT to
itself, I have caught one thread waiting in start_exclusive, and all
of the others blocked in exclusive_idle. I look at that and think
there's a bug in our start_exclusive locking, but I can't prove it.
