Well, IIRC its been proposed before, but nobody has been bothered to do it. :)


BTW, don't the GLib have something like that already?

Yeah, IIRC thats the sticking point we got to last time it was discussed :)

As Enrico said, "Glad you volunteered" :)

A final comment is that since SIGTERM is generated by desktop
environments when logging out, the whole handling and saving needs to
be *fast* because the DEs don't seem to be very patient before they
sigkill the process, and that can lose file contents when the save is
partly complete.
