... So fixing security failures is 'anticompetitive' in McAfee's
book??  Wow...  That is the kind of business that if i had the funds I
would buy just to dismantle... I knew they were bad but didn't know
they were *that* bad.

Installed a fresh VM with a Windows XP 64 bit ISO, sp2 already
applied.  VM has 512 MB ram, and the only package I installed after
the OS was cygwin.  Issue presents in this environment as soon as
Firefox connects/starts.  Page Faults Delta over 5,000 minimum anytime
I'm doing anything in Firefox, including typing this message, usually
over 10,000.

Then I went to the services applet and started disabling anything not
needed to run the X server and get the connection to/from the remote
host.  Once nearly everything was disabled, i rebooted the VM.
Currently there are only four Windows services running.  They are:
"CYGWIN sshd," "DHCP Client," "Plug and Play," and "Remote Procedure
Call (RPC)."  Issue still presents.  I've attached the XWin log and
the cygcheck output from the VM.
