Interesting - I haven't looked very closely at the code, but I didn't
realise that more than one thread was in communication with the
remote end. If that's true then theres always a possibility for mixed
data if you are sending it in chunks surely ?

Where is the potential other write occuring ? I might try wrapping some
locking round the calls to see what happens.
