Please provide an option to simply not intercept the signals that cause 
a panic.

The SAMBA signal handler is interfering with platforms like OpenVMS that 
have a built in "panic action" handler.

When you intercept a fatal signal, instead of getting a stack dump like 
you want to provide, I get a stack dump telling me that that SAMBA 
deliberately exited from the signal handler, and I do not get much in 
the way of a clue as to why the signal handler was invoked.

Since I can not run the configure scripts, it makes it easier for me if 
the default action is to assume that the operating system has a "panic 
action" handler that will produce a traceback dump.
