My feeling is that this is a serious issue that will impact pretty much
everyone using NTLM authentication.

I suspect that this is the problem, and I hope that the fix is as simple as
setting http.keepAlive = "true". I'm awaiting feedback from the reporter.

If it works, I'd opt for hard-setting http.keepAlive = true, and keeping
the current version of http client.

Not sure what the motivation for the original upgrade to 4.2.2 was: PeterN
made this change soon after we branched for 1.3. But certainly downgrading
to 4.2.1 would be safer than upgrading to 4.2.3 methinks (pretty major
changes in that upgrade).
