I realize it won't work out of the box, but has anyone given any
thought to putting the cache in tmpfs?

Seems like this might be the best of both worlds - when the system is low
on RAM it can use swap, but when you've got plenty of RAM you avoid the
overhead of writing the cache files to disk.

more flexible than memcache, faster than disk cache.  My understanding
(limited) of the tmpfs on linux suggests that it might be an easy change
to make in the code for someone who understood the data structions better
than i do ;)

mostly, just curious...can anyone say?
