BioJava uses a visitor pattern. In effect an iterator.
With all current implementations IO runs, then code, the IO, etc.
While we are IO constrained, we are actually doing worse.
What I want is an IO thread going at maximum throughput. Every item
should get parcelled out for further parsing and processing, in
parallel to the IO thread.
We should do better, and make it a generalization. I think we can do
it by using Scala and the standard BioJava iterators. With Scala it
can be turned in a parallelized iterator. That is a fun project.

All you need is love :)
