vi alarm signals

it seems that vi contains a software watchdog of sorts.
the intent is that if a vi command runs too long, a SIGALRM
will be generated, and the result will be much as if the user
hit ^C -- the operation will be aborted, and the editor will go
back to waiting for input.
now, i don't quite know why this was implemented, but:
a) the current timeout is 3 seconds. this feels too short,
especially when you're searching for a string in a long
file.
b) currently, the alarm signal isn't even caught, so when the
timer expires, the editor just dies. there's a comment in
the code that implies this wasn't always the case, so i
assume it's a recent bug.
what should i do?
the obvious minimal change is simply to lengthen the timer, to
something more reasonable than 3 seconds. the signal should also
be caught correctly.
but, should i simply delete this code? make it configurable? put
it inside a developer-only ifdef of some sort?
