My original test was capped at 384Kbps (i.e. 48KBps). I have tried it
with 256Kbps (32KBps), 128Kbps (16KBps), etc. I have also managed to
sustain HTTP and FTP connections to my server at 500+Kbps for days at
a time with no problems before.  If upload was a problem, I would
expect this usage situation to cause problems as well.  More
importantly,  I do not experience the latency when I am simply
"seeding" (only uploading).  I only have this problem when BitTorrent
is making large numbers of connections to download.

I had some extra time today, and swapped out the OpenBSD box for a
NetGear router.  I am no longer experiencing the latency problem.  I
will continue monitoring the problem for another 48 hours or so, but
my initial conclusion is that the problem is with the OpenBSD box.
Either this is a hardware problem with my box, or it is a software
bug.  Given the number of posts experiencing difficulty with
BitTorrent I am inclined toward the latter as opposed to the former.

I'm going to see if I can get another OpenBSD box to test this on, but
it won't be a Blade100.  I can also try adding an extra network card
and not using gem0 (the interface with the problem).  But that's the
best I'm going to be able to do from this end.
