- use daemon(8) to write out a pid file for processes,
and check for for the existence of that file after
killing processes
- use explict named parameters to jail(8)
Even though jail is part of the base system, it can be disabled by src.conf
settings. Therefore, it should be listed as a required program for tests
that use it.

Interestingly, the pkill tool lives in bin, not usr.bin. Haven't bothered
to check if this is because the tool moved or because the tests were
originally added in the wrong place.
