Very, very bad idea. file:/// access is intended only for single-user,
local, testing/debugging usage. Over a network, and with multiple
users, is a very quick & easy route to repository corruption or
complete loss.

No (it'll be marginally slower), but it'd be safer. And (IMO, anyway)
with a source control system, safety trumps speed.

file:/// should be atomic just like svn:// - but when you're using it
the way you are, weird things can happen.

But you should care about it. With file:///, one errant keypress can
delete or corrupt your whole repository; all users require full,
unrestricted access to the repository DB in this mode.
