It is already safe, though only a careful examination of the code shows why. The reason is, surprisingly, because it is only safe to add metrics to the metrics tree during single-threaded operation. This is because there is no mutex or other synchronization guarding it. Since it's only safe to add during single-threaded operation, the check-and-instantiate behavior is OK.
