Add lockfile to process-quarantine.pl

[rjl]

The process-quarantine.pl script should check for the presence of a lockfile before running, and write one if none exists. This should prevent overlapping runs of the script when a scheduled job runs long enough to interfere with the next scheduled run.

In the meantime - and as a workaround - I use a wrapper script such as :

*** SCRIPT *** #!/bin/bash

LOCKFILE='/var/run/amavis/pq.lock'

if [ "x$1" = "xcleanup" ] ; then

rm -f $LOCKFILE exit 0

fi

if [ -f $LOCKFILE ] ; then

exit 0

fi

touch $LOCKFILE

/var/amavisd/maia/scripts/process-quarantine.pl

rm -f $LOCKFILE *** END SCRIPT ***

This script is called with "cleanup" at boot time so that any spurious lockfile is removed

Of course, the lockfile and the script must be adjusted to match the local installation.
