BUG 1:
If you've enabled history in makefile.tmpl (with ncurses/readline libs) and
you press "Delete" in debugger you get a seg fault. -> I think that a fkt is
called then ... i've initialised no fkt...

BUG 2:
If you stop emulation with CTRL C there can be a seg fault.
This happens in the display asm stuff (sw_renderer.S).
-> Guenther?
SOLUTION:
Use sw_renderer.c (this is the default).

BUG 3 ???:
The signal handler stuff has changed in linux kernel v2.2.x.
Now it is in BSD style instead of SYSV style.
In SYSV style the handler was removed if it was called - so you had to set it
agein in the handler itself.
BSD does not remove the handler.
I dont know if it makes any differences.
