I tested the unison command using Cygwin's unison 2.31.4-2 under tcsh and it worked fine. I tested various combinations with pipes created by a native application and with native applications on send and receive side of a Cygwin pipe and all my testcases worked as expected. So, maybe we should really give it a try again.
