Right, a complicated thing to overcome an even worse (but cheap) thing.

But surely this all misses the point - two cycles are needed for a load
and store because these operations require both an instruction fetch and a
memory read/write in the same instruction, to/from the same memory.  So
that's why it seems to me that putting a cache in the way would just slow
things down, not speed them up.
