IMO performance should be taken out of the equation by using the
Readable interface[1]. That way the users can use whatever
implementation suits them (for example using an underlying buffered
InputStream) to change/improve performance.

I you mean that the performance of BufferedReader should be taken out of the equation then I agree. All CSV parsers should be compared with the same input source, otherwise the comparison isn't fair.

Using Readable would be really nice, but that's very low level. We would have to build line reading and mark/reset on top of that, that's almost equivalent to reimplementing BufferedReader.

If [io] could provide a BufferedReader implementation that:
- takes a Readable in the constructor
- does not synchronize reads
- recognizes unicode line separators (and the classic ones)

then I buy it right away!
