        Is it possible with Exim’s Perl integration to create a reference that

        I’d like to explore an flock-based lock for mail delivery that would 
allow an external process to suspend delivery by holding a lock on a designated 
path: if Exim/Perl does flock($fh, LOCK_SH) and fails EAGAIN, then Exim will 
defer acceptance of the message.

I think you're being over-complicated.

You only seem to need some form of expansion that you can run from an ACL
which results in a defer.  The expansion could be perl, could be file-existence,
could be a DB lookup.  There's no need to delce into locking.
