Try the pymongo docs for the command method - it talks about the
different ways to call the method.

This is such a common question, and such a common thing to want to do,
that it would be really nice if all of the various drivers had
universal top-level support for something like conn.lock and
conn.unlock.
It should not be this difficult to figure out how to safely back up
the db.
