No. It doesn't make sense - there's no sensible reason to use the initial
buffer except when the stream ISN'T seekable anyway, given the way the
vorbisfile API is designed.
Also, then vorbisfile has to keep this data around until ov_close(), which
isn't needed in the current design. Doing this would hurt anyone using
the initial buffer for its intended purpose, for a trivial advantage
(implementing sensible callbacks here shouldn't take more than about
1 minute for your simple case. Maybe 2 minutes.). Do it the right way,
rather than abusing a facility provided for other reasons.
