OK in addition to the bisection I've collected trace data for the good
(commit 4d770ccf4257b23a7ca2a85de1b1c22657b581d8) and bad (commit
e261f51f25b98c213e0b3d7f2109b117d714f69d) cases.

Attached is a file called trace.tar.bz2 inside you'll find 4 files, for
the two sessions:

  bad-wireshark
  bad-strace

  good-wireshark
  good-strace

From a quick glance the difference seems to be the bad case does an
UNSTABLE NFS WRITE call.  I don't really know what that means or what
its semantics are... but that bad commit does seem to introduce this
regression.

Anything else I can provide?

Thanks!
