There is a better solution to that particular problem. I use the
following script called "/usr/local/bin/procmail" in ".forward" files:

#!/bin/sh
export PATH=/bin:/usr/bin:/usr/local/bin:/usr/pkg/bin:/sbin

PROCMAIL=/usr/pkg/bin/procmail
SPAMASS=/usr/pkg/bin/spamassassin

if [ ! -x $PROCMAIL ] || [ ! -x $SPAMASS ]
then
        exit 75
fi

if [ $(sysctl -n vm.loadavg | awk '{ print $2*100.0; }') -gt 800 ]
then
        exit 75
fi

exec $PROCMAIL "$@"

exit 75

It keeps e-mails in the queue if the load is too high or the real
"procmail" or "spamassassin" are missing.

        Kind regards
