Bug ID: 52105
           Summary: Handle to \Device\NamedPipe\ cannot be used as the
                    RootDirectory for NtCreateNamedPipeFile
           Product: Wine
           Version: 6.22

                OS: Linux
            Status: UNCONFIRMED

Commit 2600ecd4edf (server: Use a separated object for each opened named pipe
device file., 2018-10-29) split the role of the named pipe device and the named
pipe file.

However, in doing so, it changed the semantics of opening \Device\NamedPipe. 
In particular, it is no longer possible to use a handle to \Device\NamedPipe\
as RootDirectory when creating a named pipe.

This bug makes Cygwin's named pipe creation
(https://github.com/cygwin/cygwin/blob/4f47e64b11ed8d47c62fa89e9b971f44b7e9ab...)
loop forever.
