Please take a look.

This looks nice, but there's very relevant logic in mgo_test that should remain.
I've avoided a non-trivial number of bugs by being told immediately when a
session wasn't properly closed.

LGTM

Would you mind to just unify the two suites into one before merging?

We don't need two different suites just to have a MgoSession parameter on it. We
can trivially have a Session (no need for the Mgo prefix) field on the one suite
we have.
