Subroutine NULL_MFS(CODE, BFS, HANDLE, NAME, FMC, RECORD, STATUS)

/* Name : SYSLISTS_MFS
* Description:
* Cache Temporary lists in memory to speed selects, reduce load on network, reduce GFE chances

* Open -- put the cache number in the handle
* Read/Reado -- add the record to the cache
* write/delete/clear -- Update remote, local copy
* omnievent -- fullcache
*
*
* Side Effects:
* Search of lists file will not show temp lists
*

* On open, connect to a cache
* Use a "namespace" prefix to separate this table's data from another
* namespace rule is crc32 of handle+tablename, so if they attach the same table with a different volume they see different data

* Note - to "clear" a table from memcached you change the namespace
* If we ever want to support clear_Table, we must make clear_table change the namespace, perhaps we use handle + name + a clear_counter in the dict.
