That would work for first exception, but the second would go straight to 
parachute. Perhaps we should change the parachute() itself to call 
OnRun() instead of MainLoop().

I didn't, but on Linux it never gets caught there. The reason is that a 
soon as it hits gtk code, the handler in OnRun becomes obsolete, and the 
only thing that could stop it is the parachute.

Could you please try to return the while() loop in OnRun and see if that 
helps? IIRC that did the trick for Borland when I initially coded it.
