Description Gustavo J. A. M. Carneiro 2010-03-05 09:24:51 EST

I later realized UdpSocket had the same problem.  Unlimited queues are evil.

+++ This bug was initially created as a clone of Bug #832 +++

It appears there's a receive queue in PacketSocket.  This queue is unlimited by default.

1. Unlimited by default is highly unrealistic;

2. Why is there a receive queue at all?  UDP sockets do not have RX queue...

This cost me days of debugging *sigh*  I had already filed a bug for TCP tx buffer being unlimited, but did not realize at the time that the packet socket had an equally evil infinite queue :-|

Re-titling to make it more generic.
