I think it is at least to the point where commercial code would be
released - free software never has any pressure to make claims
of stability even when they can...   A lot of places are using it in
production just to avoid the possibility of a slow fsck after a crash,
but it is enormously faster at creating and deleting files too because
everything is indexed so it would be an ideal stash for fast changing
session data.   If you don't trust it for the whole system you can just
use it on one partition for the session database.   Several Linux
distributions include it now.
