With this many subscribers, have you thought about interfacing Mj with
a database like MySQL? This would be faster, and instead of having
to regenerate the db file from a huge textfile every time there's an
(un)zubscribe, you could issue a single insert/delete command to the
SQL server. OTOH, you'd then be creating a dependency on another
piece of software.
