Right, but right now what Manx does is call _abort() if it detects any of
SIGB_CTRL* have been set when you do a stdio call. It would be easy enough
to have it call whatever you've set SIGINT and SIGQUIT to instead. It'd be
a step in the right direction.

Besides, I'm sure I could get SIGSEGV in a library routine if I tried :->.
