tests where exit is success

[Antti Kantee <pooka%cs.hut.fi@localhost>]

Hi,

Is it possible to write a test case where success is determined by the
test program exiting?  It is possible to define an expected failure
where the test exits, but what about expected success?

The simplest example is testing that exit(3) exits.  However, I am
working on something a little more complicated: a watchdog library.
