Yes, %d.  I have a panic action that opens an xterm with gdb already in
it.

What I think would be nice is if we could make the stdout/stderr of
'panic action' end up in the current logfile.  That should not be that
hard actually...

Then, by using echo "bt full" | gdb /proc/%d/exe %d  we have the
backtrace in the logfile.  The tricky bit is getting the path to the exe
and the gdb stuff portably, not the actual script.

Watch out, this script is open to symlink attacks - the $$ is
predictable.
