     * New waiters arriving concurrently with the group switching will all go
       into G2 until we atomically make the switch.  Waiters existing in G2
       are not affected.
     * Waiters in G1 will be closed out immediately by the advancing of
       __g_signals to the next "lowseq" (low 31 bits of the new g1_start),
       which will prevent waiters from blocking using a futex on
       __g_signals since it provides enough signals for all possible
       remaining waiters.  As a result, they can each consume a signal
