eh, close enough for jazz.

Excellent. You previously mentioned pidof, but said that
it wouldn't work. I didn't test that statement.

I don't know which one would be faster. Speed really isn't
an issue in this case though, is it? You only need to get
the pid when you run the rc script, and that is (hopefully)
not a regular occurrence. Also, the time it takes to scan
the process list is probably trivial when compared with the
time it takes to restart qmail-send.
If the qmail-rcfile file is already set up to look for the
qmail pid, changing where it looks for it is a simple
search and replace. You have to change the file anyway if
you're implementing the qmail.pid solution, and pidof saves
you the trouble of adding the (admittedly minor) pid
recording function.
pidof, a win by 44 characters?
cheers,
