With that in mind, I would propose that we take on this item as a wg
item (i.e., have the wg polled about it), and then converge on a fix (or
possible fixes). -- it's an I-D.. we don't need to agree on all minor
details at this stage.

The worst possible outcome is doing nothing about this item. So some fix
is better than no fix at all.

And since we're heading towards revising RFC793, it's even more
important that we get this done... It would be a shame to produce a
revision of RC793 that does not address this well-known bug.

Thanks!

Cheers,
