procmail and shell script sharing lockfile for a *directory* ??

I would like procmail and a shell script to share a lockfile (I was to
prevent procmail from writing to a directory if the shell script has locked
it.

The shell script lockfile is $HOME/TEMP/parse.sh.lock

The hitch is that I need to protect a *directory*

The name of the **directory** to which procmail delivers is
'Arooooo-Archive'

I'm not even sure I can lock a directory, but this doesn't give an error

:0c :$HOME/TEMP/parse.sh.lock
Arooooo-Archive

Is that really doing what I think it is?

procmail v3.22 2001/09/10

ps -- the shell script uses this code:

LOCKFILE=$TEMP/$NAME.lock

        # If the lockfile is found
if [ -f "$LOCKFILE" ]; then

# yadda yadda yadda

else
        # If the lockfile is not found, make it
        touch $LOCKFILE
fi


if there is a better way, please let me know!
