Certainly not unique. My guess is that nobody worried about a
(possibly small) performance penalty, and instead used simpler
strategies. Or they gave up libsndfile, or they never used libsndfile
in the first place (e.g. due to the scaling factors issue).

Given the virtual I/O layer in libsndfile, this is superfluous (and,
furthermore, a userspace cache adds an extra layer of copying, which
in *other* use cases could reduce performance).

I know. Maybe I messed something up -- I don't have copies anymore.
However if that were the case the message I sent two weeks ago should
have bounced back too.

The main problem that I see though is the lack of a mailing list
archive. So let's continue on LAD.
