Agreed, but I have to say that I do understand the point of view that
things should be released when ready and not before.
I also want to take this opportunity to thank the hotspot engineers - the
trend of continual incremental performance improvements in hotspot

A word of caution: I was still able to semi-reliably trigger segfaults
in a 6u18 beta with G1 during my last test cycle of it a month or so ago.
When 6u18 goes gold I'll rerun the tests and see if they still persist
let the group know the results).
