This renegotiation issue was solved on serf trunk in r2078, details in
the ticket you opened:
https://code.google.com/p/serf/issues/detail?id=114

r2078 applies cleanly to the serf 1.3.x branch, so if you can validate
the fix before I backport it to 1.3.x that'd be much appreciated!

thanks,

Lieven
