Yep... that sucks.

Yep, but I think its the only "easy way" to work around this
issue. Other options require much more time to implement :(

We also got some bad experiences with it, for example, a couple of
months ago we were using disk_list object extensively (its a "list"
that's persisted to disk using sqlite) and by replacing it with a
bloom filter we increased performance of the framework in ~15%

Ok, you convinced me. Lets re-write the whole framework in ruby.
PS: Got ya! Just kidding :)
