 well, not entirely knowing the difference, i'm guessing that i'm
adding named pipe support in the kernel.  starting from
SetNamedPipeHandleState and going from there.

 comparing what i've got so far in the improvements to ReadFile,
WriteFile, NtFsControlIo etc. with the way that it is believed that
this _should_ be done, what is right and what is wrong?
