Good summary. Thanks! Note that you could also use BerkeleyDB
(interface to version 2 & 3 of Berkeley DB library), which manages its
own locks at a page level using shared memory. I haven't used this
under load, so I can't vouch for it yet, but it looks like a great
solution for sites that run on one machine.
