DTV is differently broken, but still unusable if I revert the cache_block 
rewrite, so I cannot test that.

However, this simple patch below gets cache_block 60% functions and 72% lines 
coverage with the existing test suite. It fails currently, it fails with the 
patch 1/2 below and it passes witout 9a725a039d8cfcf91aabad0101da1563a627493f.
