I dimly recall reading somewhere, possibly in documentation about
the AE object model, that an application would register callbacks
to be used to access its objects. I can no longer find this reference.
If all the communication happens through AppleEvents, then there's
no problem. If some of it is done by callbacks, then, if any of the
callbacks run Lisp code (e.g. DEFPASCAL), these callbacks must not
happen while the garbage collector is running.
(set-gc-event-check-enabled-p nil) will prevent callbacks while the
GC is running.

I may have raised an alarm about a non-existent condition. As Rosanne
Rosanadanna used to say, "Never mind."
