Bug #12280: IO.copy_stream(IO, IO) fails with "pread() not implemented"

----------------------------------------
IO.copy_stream on Windows with IO having an offset fails with:
NotImplementedError: pread() not implemented

This seems suboptimal, should a clearer be reported?
Is it a platform limitation?
