> by the way, is this ehavior special to 9front? 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.
