Wouldn't time information in millisecond resolution be enough? That still works
fine.

Well, Tremor is designed for embedded use, so it shouldn't be that bad, I
hope. But I haven't looked much at it yet, I must admit. :) And there's
that thing with Rockbox and malloc (or the lack thereof) that needs to be
handled as well.

Actually, I looked a bit at that first, but it wasn't really a good option either.
You need most of the stuff in the four files I mentioned, so it seems easier,
from a maintenance point of view, to just add that relatively small number
of defines (a dozen, to be exact).
