exception trap in key snooper callback

[Kevin Ryde <user42 zip com au>]

I had an error in some key snooper callback code and hoped it might trap
to the installed "exception_handler" instead of aborting the program.
Is there a reason the "GPerlClosure" and "GPerlCallback" stuff differ in
that trapping?
