Doesn't auto-expire run every <n> minutes? It seems that if free space
dips below this threshold during the making of a recording, then
auto-expire should kick in to free up some more space.

If your bitrate is wildly variable, then it seems like the solution is
to simply decrease <n> (e.g., have auto-expire make more frequent

It also means that Myth doesn't need to know the eventual size of the
recording, since it's checking for free space every so often anyway.
