So even if we did that, WHAT WOULD BE THE UPSIDE?
Code that cares wouldn't run on any other Unix, or on any older
version of Linux.
And I claim that there is not a single reason to do it anyway. That
whole "code that cares" is totally theoretical. Such code simply
doesn't exist.
If you just opened a directory, and then did a "rmdir()" on that
directory, then you're just a f*cking moron if you go around saying
"ok, let me now do an fstat() on that fd to see if it really got
deleted or not". That's just _stupid_.
Really. There is absolutely no point in introducing a new rule that
nobody cares about, that we haven't followed ourselves historically,
and that would require us to play insane hacky games.
WHY DO IT? WHY CARE? WHY, WHY, WHY?
