Window-close not killing everything

I have a user of “simple_ra” that has an issue with pieces of it still
running after they use the “window close” button. In particular,
there’s an XMLRPC
server thread that gets left behind. On my own, Fedora 14, system
here, it’s not a problem. Window close kills everything. On his Ubuntu
system, it seems to kill off most of it, but there’s this dangler
that is holding the XMLRPC socket.

If I bind a “close” button to a function that issue a signal-to-self,
what signal should that be? SIGHUP?
