What version is this? I think you're hitting the concurrency bug. This is
fixed in 2.0pre3. We would do a 1.52 but we're so close to release time
that it seems silly to do so.
I've patched this for 2 client thus far by grabbing the 1_5 branch and
replacing LittleEndian roughly with the one from the 2_0 branch.
Theoretically this could also be a really slow filesystem (NFS)...
