a mod may never hit the worm.  iirc there's a memory
cache, a magnetic cache and then the worm.  even munging
a block only gets a new copy of the block should it hit
the worm.

the file-server is cleverly constructed so that only
the tree and modified blocks chew up worm blocks.  put
the calculations in the chunk of code that burns worm
blocks.

you can't code against stupidity.  that is the 'knife school'
of design.  are you sure you want to cut that?
