Do you want me to add all of the other functions that we've added to Backend
(such as lock_with) as well?

FWIW: it doesn't look too difficult, the only thing that would really need to
be changed would be the `GlobalGuard` type. Normally the lifetime of the inner
Guard would always be 'static, but with a function like lock_with() we would
want the lifetime of the Guard to match the lifetime of the provided context
instead of the lock.
