Follow-up Comment #3:

OK, the very slow data rate explains the problem.  There is no bug.  In 68
minutes the packet in question will be retransmitted.  This is just the TCP
way of doing things.

If you were to configure a smaller window, it would take much less time to
fill, and you'd get the behaviour you expect.  The window should be sized to
hold one round trip time of data at the data rate you expect, which for you
is just a few bytes!  Setting it to (for example) your MSS, and setting a
small MSS if you really are just sending 1 byte packets, would probably
help.

Closing this bug as invalid.
