I've been trying to debug #15813 and modified the Store in a way to keep unique request IDs in the .lck file. That way, I was hoping to find out which request is blocking and/or if the request is actually still running.
It turned out that `is_file()` would claim that a lock file still exists, but a subsequent attempt to read the information from that file returned "file not found" errors.
So, my assumption is that the `is_file()` result is based on the fstat cache and wrong once a process has seen the lock file.
@jakzal said in https://github.com/symfony/symfony/issues/15813#issuecomment-149013691 that `unlink()`ing the lock file should clear the statcache, but I doubt this is true across PHP processes.
