You suffer this penalty no matter what.  Ideally you would spread it out
over time (incrementally building it at package install time, for
instance).

Yeah, but this is largely an irrelevant implementation detail.  Exactly
how it's stored and read in will require some profiling; my point is
that it's probably a simpler path than requiring a daemon and having a
fallback.
