I've tried ACL cache on shared memory, tests say that it's not faster 
then MySQL queries.
Test of CPAN modules that implements cache in shared memory say that 
there is no good(fast, portable and solid) module.
I was very disappointed.

I see another variant: drop cache after each HTTP request. It wouldn't 
give much penalties and resolve this issue.

ps: I think someone from BestPractical should talk with Perrin Harkins 
he had eaten dog on caching in mod_perl evironment.
