Should be fixed now on master.

Making kill_xwidget call catch_child_signal wasn't enough, since GLib
was resetting SIGCHLD inside a timer set by WebKitGTK and about a dozen
other places as well, hence the very ugly (and unreliable) hack on
master.

It's a temporary solution that just motivated me to look at making Emacs
use GLib for handling subprocesses.
