Well, I still can't reproduce this. I've run 90 concurrent clients (from
Linux) against a CGI (on NT with 1.3b6-dev)) that sleeps for two seconds
and it doesn't hang. Well actually it does after a few 1000's of requests,
but that is more likely a resource issue (I also get a few "Connection
refused"  messages when multiple requests as initiated at the same time,
but Apache doesn't have much control over that).

Is there any significance in that fact that your test and the reporter
of the PR both used clients on the same machine as the server?

That could make sense if you are hitting upon some bug in Microsoft's
loopback code in the TCP/IP stack..  Gasp!  A bug in Microsoft's code?

Errr ... why does the hang you do get not count?
