Many of the CDC Cyber machines of the high side of the 170 series used banked
memories, along with multiple functional units.  Once in a while you would run 
into an algorithm that would get into phase with itself and try to make all 
memory accesses from the same bank, and would be mysteriously slow.  These
were -real FUN- to fix.
