No, Microsoft decided to basically change the preferred method for
applications to talk to each other with the release of win2k. while Winnt
had fast IPC, (the IPC that cygwin uses relies on it) 2k had much slower
stock IPC. There are a few articles floating around the net about it.
It's one of the reasons many older NT servers are still running, because
the software running on them will be slower on machines running 2k and
above.
