Great!
There will be a small performance hit, as each call to readByte() will 
need to first check whether it's overflowed the current buffer, right?

While trying some test runs I found that the current version fails a test:
    [junit] Testsuite: org.apache.lucene.index.TestCompoundFile
Thanks for testing this!
I'm testing the version with multiple buffers using a smaller maximum
buffer size (1024 * 128), and it does this test in the same way.
You mean it fails too?
I have not yet looked into TestCompoundFile. When it is a good test
case for this, I'll submit the multibuffer version as an enhancement.
Thanks, that would be great.
