Question: Is this throttler composable/chainable?

[dossy]

Is this throttler composable/chainable? Can I wrap one in another?

In other words: Can I use this in some layered fashion that implements both a N per second throttle but also a M per minute throttle?

For example: No more than 3 concurrent requests per second and no more than 100 requests per minute.

I think the answer is "no" but maybe there's a clean way of combining/layering/composing this that could yield such functionality?

I love how simple this implementation is and I don't want to complicate it with such features, but if a chain of these can be used to implement such functionality, that would be awesome. I'm just not experienced enough at Python to see how to.
