generators do not need to be reiterable.

lists are reiterable, but I wouldn't expect a socket (treated as a file) to be.

For a queue that is already sorted, the natural use case is to take
the task and do it, explicitly adding it back to the end if need be.
I would expect an operation that *didn't* remove things from the queue
to have view in the name somewhere.
