Do you really need to call ConnectNamedPipe() at stream_behavior.hpp, line 258? AFAICS, at that time the client's end of pipe is opened already, so there is no need to wait for it.
If I remember correctly ConnectNamedPipe() is called to make sure that both ends are connected before the constructor of boost::process::behavior::named_pipe returns. As CreateFileA() is called with FILE_FLAG_OVERLAPPED this function could return immediately
It couldn't because it returns "... an open handle to the specified file, device, named pipe, or mail slot ..."
I commented out the code and ran the relevant test cases a couple of times on Windows - they were all passed successfully. I don't know whether I misinterpreted anything on MSDN and thought that because of passing FILE_FLAG_OVERLAPPED to CreateFile() this function could also return immediately. I guess it's then safe to remove the call to ConnectNamedPipe() (if not we simply revert to the old version in Subversion :-). Boris
