We appear to have some big TCP problems in -stable (and presumably in
-current as well).  Anyone wishing to look at traces is welcome to
retrieve http://khavrinen.lcs.mit.edu/test{,2,3,4}.tcpd and take a
look.  Warning: these files are very, very large:

 95M    test.tcpd
108M    test2.tcpd
107M    test3.tcpd
 15M    test4.tcpd

Each trace shows a single large file transfer from a 4.4-stable
machine to my -current desktop over a local-area network.  test4 was
aborted about 10% into the transfer so that you have a chance at
looking at the whole thing in xplot.  There are multiple pathologies
visible in the results, but a good place to start would be around
:56.44 in test4.
