To be clear, it's not implementing RFC 1323 (and not even *not*
implementing 7323) that causes the issue. 1323 actually didn't specify
what to do with non-timestamped segments on a timestamp-negotiated
connection, and illumos pre-5850 did something very surprising which I
doubt nobody else did (stop generating timestamps on all future
segments), so I don't think you will be able to reproduce the hang with
other operating systems, but you'll likely be able to see the unexpected
non-timestamped segments in connections between other OSes as well (but
I still can't be sure because I don't know what middlebox is injecting
them or why :)
