Hi Eric,

if I use kill -11, I would be really surprised to see
the process freeze.

It would be good to look at siginfo->si_code
and _not_ continue the normal exception handling
when the si_code is SI_USER or anything <= 0.

If you receive a signal 11, with si_code == SI_USER,
you can be sure that is sent directly from me,
and I want the process to immediately stop doing what it does
currently and create a core file for later analysis.

I found a pointer in the internet, how to
handle SIGSEGV and still create a code file,
sounds interesting.

The idea is to just set the signal hander back to default
and raise the signal again.

Bernd.
