const char* get_panic_action

(

void

)

This routine catches signals and tries to send them to gdb.

Because it's called from inside a signal handler it ought not to use too many library routines.

TODO:

Perhaps use "screen -X" instead/as well, to help people debugging without easy access to X. Perhaps use an environment variable, or just call a script?

TODO:

The /proc/ magic probably only works on Linux (and Solaris?) Can we be more portable?
