Yes well,
FlashForth was designed to hold your hand to a degree.
Specifically the idea was  to make it impossible to nuke the FF kernel.
Having to re-flash the kernel all the time would be a nuisance, and ugly.

0 BASE ! nuked the kernel somehow, but now 5.0 catches divide by 0 
exceptions so that is not a problem.
Not even EMPTY helped, I dont really understand why, since the kernel is 
write protected, but now it will never happen.

1 BASE ! does not nuke it, but on PIC18 writes some crapola into eeprom, 
so that you
can only recover with EMPTY. On PIC24 and Atmega a restart is enough to 
clear the situation.

I guess all the other bases are fine ($2-$ffff).
