It copies diligently for the first 20-40MB (exactly where it stops varies from run to run), then CPU usage drops to zero, the file stops growing on the receiving end, there's no apparent network traffic, and everything just pretty much halts.  A ps shows the scp task running, but not doing anything.

Hmm, that doesn't happen for me.  I tried to copy around a 200 Megs file
between WinXP and XP<->Linux multiple times and don't see any hang.  Did
you try with Cygwin 1.5.12, too?
