Not in the Cygwin DLL. As an extra DLL layer I don't have a problem with that. > P.P.S. Perhaps the answer to (*) is NO, otherwise we would have fast > fork()... That's not quite correct. The problem is not utilizing the native NT functions to create a process image, the problem is that the Win32 libraries like advapi32, msvcrt, etc, which are directly or indirectly loaded into a Cygwin process, are not capable to deal with a process clone situation. They were never designed this way and there's not much chance they will ever get a revamp, just to allow Cygwin to create a fast fork.
