This is in general the best way to do it we've come up with.

Another way to do it is to write a custom main loop source 
that checks a flag in its prepare/check methods to see whether a
dispatch is needed. But this relies on the fact that 
your signal wakes up the main loop poll() or select() with an EINTR, 
and there was some issue with that which I don't remember now.

If you search the gtk-devel-list archives you can probably find at
least a little bit of discussion on the topic.
