Yes, the specific case I had in mind involved this sequence of events:

 * run method of modal dialog #1 called
 * hide dialog #1
 * run method of modal dialog #2 called


Answering my own question: Looking at the code, gtk_widget_set_visible 
just calls gtk_widget_hide.  That unmaps the dialog, which causes 
GtkDialog's unmap callback to run, which ends the recursive event loop. 
Connecting a unmap signal handler that stops the unmap signal seems to 
work: I'm able to hide and re-show my modal dialog.
