Yet another POSIX deficiency.
When a server deals with 10,000,000+ socks, we absolutely do not care of
this requirement.
O(log(n)) is still crazy if it involves O(log(n)) cache misses.
If you think it's a POSIX deficiency then logging a DR is probably the
correct way of addressing that. And as I've said it's fine to decide
that you don't care about what POSIX says on the subject but you can't
simultaneously claim POSIX conformance. One or the other, not both.
