If two modules import the same module, they get two references to that
same module, not two separate module instances. Since your parameters
appear only to affect the initialization itself, this is not likely to
be a problem (it's not like you'll need to authenticate with two
different sets of credentials, for instance), but it will mean that
the second one will import an already-initialized module. That's why I
suggested the try_init function which would quietly return an
immediate success if the module had already been initialized. But if
this isn't going to be an issue, then your code's fine.
