This is obviously an improvement, but it makes me wonder if we should be
doing:
if (!check_header(mi, &mi->inbody_header_accum, mi->s_hdr_data))
die("BUG: some explanation of why this can never happen");
which perhaps documents the intended assumptions more clearly. A comment
regarding the side effects might also be helpful.
