This comment is just in time. I will add something to the next edition.

Exim locks its spool files using fcntl(). It is locking only against
itself, so there is no need to use lock files. It would be trivial to
write a little utility program to check for locking of a spool file
(Exim locks on the -D files, not the -H ones). However, the cost of
doing this is very much the same as kicking it with -M because the first
thing that does is to see if the message is locked and if so, give up.
