Hard to say.  I don't do this stuff.  Those toolkits written in
C/C++/Objective-C usually run an event loop and it's probably a better
idea to send events to the UI thread.  Maybe
swank::*listener-eval-function* could be used for this.  That function
could tell the GUI toolkit to properly call a Lisp function in the UI

Maybe a case for *connection-closed-hook*.
