Timed self-destruct (for debugging programs that hang)

[Bennett E. Todd III]

Well, I got a few helpful responses. I appreciate everyone's forbearance
with such ugly code.

I got suggestions for good tricks to play with adb, for ways to refine
the program I wrote, and other such tips. However, the real kicker comes from:
	Stephen Samuel
	{ihnp4,ubc-visi}!alberta!uofa-mts!stephen_samuel

who gets the prize for cleverest hack of the bunch:

( sleep 120 ; kill -9 $$ ) &
exec $*

His explanation is succinct:

"What it does is have the kill delete the primary process, which is then
replaced with the real intended program. Note that this also results in
a mimimum of extra procsses and NO temporary files."

Hat's off. I guess this illustrates the basic nature of UNIX; there is
generally only one correct way to do a thing, and many many wrong ways,
most of which will occur to you before the right one.
