Version 1.7, available from:

I wrote it over a year ago for use in a production environment,
but I no longer work there, so I just maintain it.  A lot of
end users do use it in aggressive environments, though, and have
offered a number of suggestions that have improved it a great
deal over its revisions.

If you're running all of your IMP services on one machine,
though, the files-based handler will still likely be faster.

Also, the msession extension that was recently added to PHP 4 cvs
apparently offers excellent performance, but I haven't used it
personally.
