Forcing the GUI to update

[Murray Cumming <murrayc usa net>]

Can anyone tell me how to force GTK+ to update the GUI?

For instance, my signal handler does a lot of processing, so I want to
change the cursor to the "watch" cursor (with gdk_window_set_cursor()).
But that doesn't actually happen until after the signal handler has
finished.
