  Use sigaction for signals which should persist past the initial trigger, not signal.
  
  If you call signal() in a Solaris signal handler, instead of just resetting
  the signal handler, it causes the signal to refire, because the signal is not
  marked as handled prior to the signal handler being called.  This effectively
  causes Solaris to immediately exceed the threadstack in recursive signal
  handlers and crash.
