A dumb bikeshed, but would you mind naming these BOS1 and BOS0, and
perhaps consider adding a comment or pointer or link to something that
describes why we use the two different modes? I recognize that the
code already uses the two different modes already without comments,
but this might be a nice place to point folks like myself to so that
in a month or so when I forget what the difference is between modes
(again), we have a shorter trail of breadcrumbs.
