Now that the minimal runtime version is Windows 10 in v16~ thanks to
495ed0e, we could be much more aggressive and do the attached, which
is roughly what Thomas has proposed upthread at the exception of
assuming that FILE_MAP_LARGE_PAGES always exists, because updates are
forced by MS in this environment.  We could make it conditional, of
course, with an extra #ifdef painting.
