concurrent.interpreters queue documentation doesn't match reality

[da-woods]

I don't know if this is a problem with the documentation or with reality but:

• QueueEmptyError and QueueFullError don't exist (https://docs.python.org/3.14/library/concurrent.interpreters.html#concurrent.interpreters.QueueEmptyError). They appear to be called QueueEmpty and QueueFull.

• queue.get doesn't take a block keyword argument. The documentation says

  which implements the queue.Queue interface.

  and queue.Queue.get is documented as having a block method.
