There are already a number of f* functions exposed in posixmodule.c
(fstat, ftruncate, fsync, fdatasync, fstatvfs, fpathconf); a patch
adding fchown would certainly be accepted. 

If you want polymorphism, you need to come up with a way of doing it
uniformly; that would require a PEP, documentation changes, and
testsuite additions (fchown would also require documentation changes).
