cygrunsrv + sshd + rsync = 20 times too slow -- throttled?

[Chris Roehrig]

I got it to build and tried out the topic/pipe branch (checked out on Monday around 4:30pm PDT):

1.  I didn't see any improvement in my sshd+rsync time, still 3-4 MB/sec.

2.  I get the following error from procps:   procps:ps/output.c:2195: please report this bug
(I also get this using the main branch build).

I first updated my cygwin normally using setup-x86_64.exe, then built and copied only the cygwin1.dll into /bin from the install/bin directory (quitting all cygwin tasks first).
