-**  LOCKFILE -- lock a file using flock or (shudder) fcntl locking
-**
-**	Parameters:
-**		fd -- the file descriptor of the file.
-**		filename -- the file name (for error messages). [unused]
-**		ext -- the filename extension. [unused]
-**		type -- type of the lock.  Bits can be:
-**			LOCK_EX -- exclusive lock.
-**			LOCK_NB -- non-blocking.
-**			LOCK_UN -- unlock.
-**
-**	Returns:
-**		true if the lock was acquired.
-**		false otherwise.
