I started this tread from my home/office in Hawaii. I'm in the
SF Bay Area this week on business. I'm not logging in to the
machine this week - I said I'd run the suggested experments
when I got back to being in proximity to the machine. This
week I'm just responding to questions on the thread.
Its *very* unlikely the machine has been compromised. It's
not discoverable from outside my firewall (on a router), I
don't read/download mail on it and no other software has
been install on it. Its a specific use machine - building Sun
Java using the Cygwin tools.
It also only had a couple of days to be compromised from
a full, clean, install to the problem report.

I missed the "propagation" aspect.
Yes, the entire build is started from the bash command line. This may
not be the most interesting experiment because this means that everything
under the "make" will have affinity to a single processor, including the
Visual Studio tools. All that will be running on the other processor will
be background system processes (of which Windows has more than a
few).
This does make the experiment quite easy. I'll report back results when
I can.
