Database directory options

[mdcallag]

Thanks for sharing this and producing a MySQL storage engine.

My language skills are limited to English, so I can't figure this out by reading your docs.

Is the database directory always in /dev/shm? I ask because that is what your sample configs appear to do. I am interested in trying it for a database larger than memory and assume I need to get the database directory on a filesystem backed by an SSD or disk.
