    Make the low contention torture writers write

    OSSL_sleep() takes milliseconds, so the contention == 0 path slept a
    second between writes and the low contention tests managed six writes
    each in their four second budget.  The readers spun tens of millions of
    times over a value that was not changing.

    Sleep a millisecond instead.  In the same four seconds torture_rw_low
    goes from 6 writes to 4940, and torture_rcu_low from 6 to 6344.
