ronald yang commented on JGRP-1256:
-----------------------------------

it's pretty clear to me that my change won't enforce a hard limit on the xmit buf size, but I feel it's better to bail out early when a known invariant is about to be violated (highest_delivered is not supposed to exceed highest_received?).  Without this check then we have to wait for the long value to wrap around which will take a while.

Maybe the right thing to do, for trimming the xmit buf, is to count up starting from low?

> it is possible for the NakReceiverWindow to enter an infinite loop if max_xmit_buf_size has been set.
