This function is available as File\AlreadyLockedException() in Facebook's www repository.
Indicates that a lock failed, because the file is already locked
This class does not extend OS\Exception as an EWOULDBLOCK after
flock($fd, LOCK_NB) is expected rather than an error; this exception is
thrown when the caller has explicitly requested an exception for these cases.
