I've created a PR to do this. I don't know if the people who have participated in this bug
to date get emails on updates to this bug, but if you do and have thoughts on the PR I'd be
interested.

Can this please be disabled. Modern operating systems have their own stat cache that is properly
maintained. A cache on these systems reduces performance *and* causes subtle and frustrating errors.

The stat cache is cleared between requests. What you have in mind is the realpath cache.

> You guys realize that the stat cache is per-request

nonsense - it's per prcoess and "You only need to clear the stat cache before a
file_exists() call" is bullshit, you should be able to clear it *after* change a file but you
just paly lotterly for which request in the future clearstatcache() has any effect or was just a
joke

https://bugs.php.net/bug.php?id=73888 is a
deisgn error wihich makes a) the cache mostly usesless and b) clearstatcache() to a lottery game

We really need this option to disable cache in daemons, written in PHP.
WebSocket server for example. Or some worker, which listens the queue and performs some jobs.
