-/* This implementation is similar to the one used in the Linux kernel.
-   But the kernel is byte instructions for the memory access.  This is
-   faster but unusable here.  The problem is that only 128
-   threads/processes could use the spinlock at the same time.  If (by
-   a design error in the program) a thread/process would hold the
-   spinlock for a time long enough to accumulate 128 waiting
-   processes, the next one will find a positive value in the spinlock
-   and assume it is unlocked.  We cannot accept that.  */
