In the current case, the printing of the backtrace also calls exit(). I don't think "stealing" SIGQUIT is a good idea. Rather this could be implemented on the Pike-level using the Pike-level C backtrace method.

Also, remove the catching of signals in the signal handler, so the next similar signal will kill Pike. Just in case it hangs when making the backtrace...
