How can I create a 'catch all' way to catch all possible signals?

On unixoid operating systems (AIX, Linux, SunOS, ...) there is
a special signal called SIGKILL, which can't be catched at all.
With the exception of this you can try the following:
import signal, os
def mysignal_handler(signum, frame):
    print 'Signal handler called with signal', signum
for signum in range(signal.SIGHUP, signal.NSIG-1):
    if signum != signal.SIGKILL:
        signal.signal(signum, mysignal_handler)
