Every mutable collection needs to lock before write? Sounds slow af

Locks are generally very cheap if they're not contended. Of course it's all relative though!

They're cheap but they're not free. If you do it at literally every single rw operation at runtime, it's going to add up.

Last I looked, the nogil implementation was some 5-10% slower than the current, owing to all of the extra locking.
