So, this problem/question can be generalised as well. How can we get a hold

SIGCHLD...) and no widgets have been passed to signal handler functions.

You will need to keep track of the relevant toplevel windows somehow, so
you can easily access them if you need to. This could just be global variables,
or a list of toplevel windows.

Though I doubt it is safe to make calls to many GTK+ functions from within Unix
signal handlers. So be careful what you do.
