mmap_disable = yes
lock_method = fcntl

I guess we can turn mmap_disable off, since our indexes are on local FS.

We were using beta8 before, it was the only one that didnt have some
problem we couldnt live with. We've tried some RCs, but every time we
had some major problem. RC15 seems workable, but with a few issues.

I'll turn mmap_disable off. Anything else I can do?
