multiple AtomTables should be supported, benefiting multiprocessors

multiple AtomTables should be supported, along with the NUMA API (libnuma) to permit efficient use of multiprocessor systems, i.e. computers with >1 processor socket where each socket connects directly to its own bank of memory. The NUMA architecture is present in Intel's new Core i7 systems (November 2008) and is present in AMD Opteron and Phenom systems (including affordable 2-processor workstations).
