We are now diverging a bit outside Squid and into the land of TCP/IP
communication and kernel stupidities.

In TCP/IP the limitation is 65K outgoing connections per source IP and
destination:port. (source IP:port, destination IP:port combination must
be unique).

In kernel land the limitation of "anonymous" outgoing connections with
automatically assigned local endpoint is 65K in total, no matter how
many local IPs you have or how many different destinations you talk to.

In kernel land the limitation of explicitly bound outgoing connections
is 65K per local IP. (explicit bound to a local ip:port, each
different per connection)

outgoing connections == outgoing connections in any state from SYN_SENT
to TIME_WAIT, all included.
