Cool! There is a problem though. If an asynchronous signal, e.g. 
SIGALRM, is delivered to a thread that is executing vector instruction 
the application crashes with SIGILL. I assume that return-from-signal 
code path doesn't restore some processor state bit. Just in case anybody 
runs into it...

Cheers.
