The newly released Microsoft Services For Unix (SFU v3.5) includes a new
"highly tuned" POSIX subsystem. MS says that UNIX apps using the POSIX
subsystem are within 10% performance of Windows apps using the Win32
subsystem. The security models also work together so that chmod/chown/su
and friends all work properly. It would be nice to see an implementation
of setfacl and getfacl.

Would there be any benefit to porting Cygwin to sit directly on top the
POSIX subsystem instead of going through the Win32 subsystem?

kernel <-> POSIX <-> cygwin (bash, et al)

instead of

kernel <-> WIN32 <-> cygwin.dll <-> cygwin (bash, et al)

Just curious.
