Nice catch.  It's probably neater to move the call to tcp_rx_seq() above the 
call to xfer_deliver_iob(), rather than using a hack to work around the 
problem.

A consequence of making this change is that you would then have to treat 
xfer_deliver_iob() errors as fatal to the connection, but that's arguably a 
good idea anyway.
