 Using this function is the right thing to do, if your program is running
wxEventLoop, but calling it from a signal handler is almost certainly not
signal-safe (just read about the recent regreSSHion vulnerability in
OpenSSH to see what this can result in).

 You need to arrange things so that it's called from the event loop itself
when some flag is set from the signal handler.
