The current NFS client code is broken. It has been since early 2.1.x. It
makes one assumption that its safe to manipulate sockets from the received
data callback which isnt unfortunately true.

I've had a look at the area of code concerned and while its probably safe
for UDP (it may not be SMP safe) its not safe for TCP and not easily fixable
as I had hoped.

If nobody else has had time in a few weeks I may have another look at it
