They're not *bad* for size any more than page alignment in a dbm

Tools that need faster access during an operation can build
temporary databases to accelerate operation as needed, so I don't see
any problems here. I wouldn't expect that to be needed too often.

Yes. This stuff should not require any exec or eval. It might be
