Oh dear, this is getting totally confused...

to be clear, it is my belief that the original questioner's problem came
from his 8 threads all being propagated from a *windows local* connection,
which is NOT thread safe. So I advocated that he use tcp/ip local
loopback. Let's get clear of this windows-local connection - it is not
feasible for multiple threads. Local loopback uses tcp/ip; local
connection doesn't; local connection and local loopback are NOT equivalent.

As to the question of whether the server "localhost" and the IP address
"" are equivalent: yes, they are. However, in some Winsock
implementations, "" is resolved initially as a string, not as an
IP address. This can slow things down, on these older Winsocks, but they
will both eventually resolve to localhost.
