well, my experiences with APC have been pretty mixed - seems to work
really well for a while. However, I'm *all* for promoting some further
collaboration with Rasmus... and yeah APC would probably be much better
for this stuff (or memcache which has a PECL extension
http://pecl.php.net/package/memcache as well).
the big issue, though, is to have something (maybe just status quo?) for
folks that don't have a shared memory option (i.e. typical hosting
environments) - the good news is they're the ones that don't usually run
into performance issues.
all that to say +1 :)
