That was indeed my first thought, but after realizing that when squid decides
to stop ACCEPTing and the socket queue fills up and remains full at a fixed
value of 1.5 times soacceptqueue (even when no new connection attempts are
coming in and the host and squid are idle), then it becomes apparent that
the socket queue will eventually just fill up regardless of its size limit.
The analysis of the problem in the upstream bug seems to confirm this.

The queue being full is just a consequence of the application not accepting
new requests any longer.
