-  If any of the operations are not provided then we must emulate some
-  of them. That means we need a nice implementation of spin locks
-  that avoids the "one big lock" problem. We use a vector of spin
-  locks and pick which one to use based on the address of the operand
-  of the function.
-
-  To generate the index of the lock we first shift by 3 bits to get
-  rid on the zero bits that result from 32 and 64 bit allignment of
-  data. We then mask off all but 5 bits and use those 5 bits as an
-  index into the table.
-
-  Picking the lock this way insures that accesses to the same data at
-  the same time will go to the same lock. OTOH, accesses to different
-  data have only a 1/32 chance of hitting the same lock. That should
-  pretty much eliminate the chances of several atomic operations on
-  different data from waiting on the same "big lock". If it isn't
-  then the table of locks can be expanded to a new size so long as
-  the new size is a power of two.
