nope. 9atom does this. i had to deal with this for 64 bit
quite a while ago, since the add to mb to the brk trick doesn't
work when your page size is 2mb. be aware if you're attaching segments
that your idea of what the page size might be may be inaccurate.
i
am not sure i read cinap's email correctly, but i'd like to
phrase the man page as [va, va+len) will be valid unless the
return value is (void*)-1. there are no promises about other
addresses just before or after this range.
