Hi Christopher - can you please share the performance testing code / results you made?

If this is indeed a performance bottleneck, we can probably contribute this back to the Java
project (although this is not in a performance critical path).

>   Original Estimate: 0h

> The Refill() method of the FastCharStream class contains logic based on an IOException
being thrown. This logic degrades the performance of every query by about 10x from my testing.
