Did you get around to trying to reverse the direction of the data flow through the pipe or any other similar testing to form a conclusion ? The problem here is that I am a Unix person, this is the principal reason why CYGWIN appeals to me. So I really dont have the motivation to "investigate" the matter and hunt down undocumented platform quirks. The FILE_PIPE_LOCAL_INFORMATION is also an undocumented use of NtQueryInformationFile. I do have the energy to work on my proposal to implement until completion but even that it a little mared by the possibility of having such a patch rejected by the committers. Unfortunately this is how open source is, no one has the right to dictate what another person spends his time working on.
