 *  Shared scratch memory buckets: most XDAIS algorithms need scratch memory,
 *  and it can be shared among more algorithms they can never be preempted
 *  by one another. By defining "buckets" of shared scratch memory we can
 *  minimize toal scratch memory requirements. When defining a cell, we
 *  set its "shared scratch bucket" to one of the values defined here.
 *  Typically, cells belonging to threads running at same priorities would
 *  go into the same scratch bucket.
