Every cron that I have ever seen or heard of either rereads crontab
every minute or so (v6 may have done this) or checks its modification
time and rereads it when it changes.  I would consider a cron that
has to be killed off and restarted when you change crontab to be
seriously brain-damaged.  Perhaps you should check whether your
supposition is really correct.
