hmm... rethinking about that, it'd be nice if we could do that, but as Evan 
noticed INSERT happens before any code - hence trapline - is known to the 
exec engine... but then we might do a trick, ie if INSERT fails, we insert
a FAULT with due arg, eg

 fault /insert file.crm: not found/

then a following TRAP could handle that.
