[Python-ideas] Adding full() to collections.deque

[Guido van Rossum]

Isn't the problem that you don't know if it's still full on the next
line? After all you supposedly have a multi-threaded app here,
otherwise why bother with any of that? Or maybe you can describe the
real-world use case where you wanted this in more detail? Without much
more evidence I can't support such a change.
