svnsync and serf -> hang

Hello,

when syncing repositories with svnsync (from trunk) using serf
(r1222 from serf trunk), svnsync eventually stalls while transferring
file data. Killing the svnsync process and respawning it causes it to
sync some more revisions, and eventually it stalls again.

I've tried several repositories as sources, including our own,
and the cvs2svn repository from tigris, and a few from sf.net.
They all had this problem.

I've ruled out an MTU issue, the server can be pinged with
larger packets than the egress interface MTU.
Also, when flipping the default http-library to neon, the problem
goes away.

Can anyone reproduce? Is this a known issue?
