> Profiling shows that BufferedRandomAccessFile.length is eating up an
> unexpected amount of cpu. It believe it is the call through the "native
> barrier" that is causing it. We often call the length method via is end of
> file when reading data. We can add caching of the file length to avoid this
> call most times.
