I did a 'git pull' of the latest topic/pipe and rebuilt and I now do indeed get 100MB/s transfers using both rsync and scp (without pipe_byte).
(It turns out last time I forgot 'make install'  -- Doh!)

I still get the procps error however.

I tried running cygsshd with CYGWIN=pipe_byte as well as empty (in the registry HKLM/SYSTEM/CurrentControlSet/Services/cygsshd/Parameters/Environment/), using net stop cygsshd + net start cygsshd to restart it.   Not sure if that CYGWIN only applies to cygsshd or to all cygwin tasks.
