I can ditch MySQL if I find something better.  It's only a module.  And
the already-written code is there to be reused in any other OSS project

The commits need to be done atomically.  What we use is complicated
queries.

Our server can run as any user you choose to.  Running the database as
another user, even if you choose to run the server as root, is in the
pipeline.  But the simple fact remains that to index every file, you
need to be at least absorbing data files as root.

Processes may be cheap.  What processes do in their bowels is not,
especially if we're talking about indexing.
