-   the first thread to do so via a CAS on once_control runs init_routine,

-   When forking the process, some threads can be interrupted during the second
-   state; they won't be present in the forked child, so we need to restart
-   initialization in the child.  To distinguish an in-progress initialization
-   from an interrupted initialization (in which case we need to reclaim the

-   can reclaim iff it differs from the current fork generation.
-   XXX: This algorithm has an ABA issue on the fork generation: If an
-   initialization is interrupted, we then fork 2^30 times (30 bits of
-   once_control are used for the fork generation), and try to initialize
-   again, we can deadlock because we can't distinguish the in-progress and
