spamassassin lock file in procmail?

["Monique Y. Herman" <spam@bounceswoosh.org>]

Procmail's documentation suggests that you only need a lockfile if the
rule delivers directly into a file, because applications should take
care of file locking on their own.  (Read this last night; can't recall
where.)

Spamassassin's INSTALL doc
http://www.spamassassin.org/full/2.6x/dist/INSTALL
suggests the following rule:

:0fw: spamassassin.lock
| /home/user/sausr/bin/spamassassin

Anyone have opinions on whether the lock file is necessary?
