Ah, yes, well, that's because we're using the same progress bar / ETA
for cached recipes as for actually parsing recipes, and obviously the
amount of time for those are quite different.  The ETA is gone until
we give thought to if we want to revamp our progress, and how best to
do so.  Ideally we'd probably use one progress bar for cache loading
and one progress bar for *actual* parsing (as opposed to processing).
