--------------------------------------+-------------------------
 If you return from a SIGFAULT, SIGFPE, SIGBUS, or SIGILL the offending
 code is re-run and the signal is raised again.

 If the fault occurs in the the UI thread where
 SignalHandler::handleSignal() is run in it will never run since we never
 get the opportunity to continue on to where the QSocketNotifier events are
 handled.

 This leads the write() in SignalHandler::signalHandler() to block forever,
 deadlocking the UI thread.
