[antlr-interest] java.g does not compile

I wouldn't change the default time out as then your project depends on a custom version of NATLR for no good reason. That was just my 6:40AM typo of course :-)
I have a QX9450 and some i7s. I think that the Xeon server versions of 9450 etc might be slower on a single thread. I think a lot of the i7s are faster than Xeon? However I haven't bothered with Xeon myself. But, it depends what you are measuring. Most of the published benchmark programs are worthless.
