Is it more CPU-efficient to read/write config file or read/write sqlite database?

Look, broadly I agree. But this thread was about sharing access to
configs etc between processes. And it segued into suggesting sqlite.
Which is good and bad.

My point here is that here we were discussing cooperative access
to some shared state. And a "database" is tossed into the mix, with
its -- for this purpose --- overkill data integrity provisions.

So I feel obliged to point out the performance costs associated
with using a sledgehammer to bang in a tack.
