Can I have a couple of quick code review for this very small
change?
<br>
<br>
<a class="moz-txt-link-freetext" href="http://cr.openjdk.java.net/~tonyp/7146246/webrev.0/">http://cr.openjdk.java.net/~tonyp/7146246/webrev.0/</a>

It turns the following two cmd line params into product params:
<br>
<br>
G1HeapWastePercent (previously called:
G1OldReclaimableThresholdPercent)
<br>
G1MixedGCCountTarget (previous called: G1MaxMixedGCNum)
<br>
<br>
These are helpful in allowing the user to fine-tune G1's behavior
wrt which old regions to collect during mixed GCs, how many mixed
GCs to do, etc.
<br>
<br>
I also increased the default value of the former from 1% to 5%.
Charlie ran some performance tests and found that the new default
eliminated some very long mixed GCs that he was experiencing with
the old default.
