Looks a lot saner... although it does seem to confirm my earlier
suspicion that you're not even _using_ the fact that it's a bitmap at
all. You set the bits for the present channels at init time, which are
always contiguous, and you never seem to change them them later -- why
couldn't you do this with a simple 'number of channels' integer?

Are you later intending to use the bitmap to mark them as busy/free?
