It would probably help with performance, but the description is a
little disconcerting in terms of crash recovery. We tried running
with it off for a while (a year or so back), but had problems with
corruption. I think the specific cause of that has since been fixed,
it's left us a bit leery of the option.

Maybe someone else can speak to how safe (or not) the current
implementation of that option is.
