Frank.

That would certainly be true and it would be up to the programmer to
make sure they didn't do anything stupid, like ignore the exception.  In
the event of such an error, the script might have some important work to
do such as return an error page (in cgi applications) or close databases
or start a pot of coffee for a late night debugging session and the
premature abort() would prevent any action.

Actually, if the error was from malloc, there could be quite a bit of
invalidation throughout the interpreter.  Maybe this wouldn't be such a
good idea.
