Summary: `PhutilFileLockException` does not exist. Per https://we.phorge.it/source/arcanist/browse/master/src/filesystem/PhutilFileLock.php$54-66 , if lock acquisition fails it is supposed to throw a `PhutilLockException` instead. Test Plan: Grep the code base. Or, run this, from arcanist, from two different terminals: php ./support/unit/lock.php asd.txt After this change, the exception is correctly managed.
