[Resending as the last copy seems to have been lost in the ether -- it
certainly isn't in the GMANE archive]

Well, behavior with the patch applied is certainly different.

The large download I'm running still times out; however, it is now able
to resume without needing to bring the interface down and back up.
However, after the first timeout, subsequent timeouts occur with much
greater frequency -- making this multi-GB download still an
impracticality when using -net tap.

The flood ping is not killing the network connection, though it is
interrupted by frequent messages: "Warning: time of day goes back
(-23150us), taking countermeasures". (This is no the high end of the
time variances shown; the smallest are on the scale of 120us).

[btw -- Wind River? heh -- 'yall were The Great Enemy back when I was at
MontaVista around 2000-2002 or so]
