On one hand, the upshot of that is that by finding an
appropriate library module you might gain some of the same
benefits as removing the GIL.

On the other hand, that doesn't help if you're doing something
original enough that nobody has written a library to handle
large chunks of it.

And on the grasping hand, I find that most of us vastly
overestimate the originality of what we're doing.
