A priorityqueue seems far more like a list than a socket though.  I'd
be very surprised if __iter__ was destructive.  If destructive is the
only option I would prefer it be a explicit method.  Especially since
it's common modify and reiterate over a priority queue, which I
believe never happens for files or sockets.
