mmap.flush returns different values for windows/unix like platforms in case
it succeeds.
mmap.flush raises an exception on unix like platforms for errors.
mmap.flush returns 0 on windows for errors. This is the value which is
returned on unix like platforms for a successful call.
The documentation for mmap.flush does not even mention a return value.

so, still: sorry no, the application should not just look at the result
being returned. The mmap.flush method should be fixed.
