As my original email stated, I could see using netstat that there were tcp connections left in the FIN_WAIT_2 state and the Apache documentation suggests this could be a bug in the client. Also as the Apache documentation suggested, disabling KeepAlive resolved the issue. See http://httpd.apache.org/docs/2.0/misc/fin_wait_2.html
The hypothesis stated here is that serf isn't closing its connections
correctly when they are closed by the server, on Windows. While I
don't think anything is wrong with that part of the serf code, serf
testing is mostly done by using short-lived processes so if there's an
issue it might not be very visible. I'll have a look later.

That's not what that mail suggests. It talks about an old bug where
svn+serf can't authenticate to a server using the Digest
authentication scheme when that server is configured with KeepAlive
off. That issue was a) solved a long time ago, and b) as others have
said is unrelated to what you're seeing.
