keepaliveNextRequest: abandoning FD

I'm working with code I obtained from Alex that was sync'ed with trunk as of -r12082 (2012-03-07 v3.2.0.16+) and on a very busy system doing forward HTTP and HTTPS proxy (but not sslBump), I am seeing lots of these messages:

I see that there was a discussion back in November about this issue, but I am not understanding what the root cause is, and whether it is indicative of a serious problem. Any thoughts?

Thank you,
Guy Helmer
