Sadly, this isn't going to work unless you give up on some security. The
daemon is running as the Exim user; it has to re-exec to get back root
privilege in order to do a delivery, unless you abandon the use of the
Exim user and run as root all the time.
I seem to recall seeing something in Perl 5.6 about compiling and saving
the bytecode.
