ext/standard/tests/file/lstat_stat_variation15.phpt fails at high concurrency

[nikic]

Regularly seeing this test fail at -j32:

005+ Error: stat1 do not match with stat2 at key value: 8
006+ Error: stat1 do not match with stat2 at key value: atime

I wonder if this is something similar to php/php-src@1e3196a (cc @alexdowad).

It seems likely.

Where is it failing? On your dev machine, or CI?

If local, what OS are you running? If you have access to a tool that allows tracing syscalls system-wide, you could quickly find out what is causing the problem.
