I mean, if compare to shrinking, growing can be agressive a little more,
we can to do grow even the launching thread get old information.

But if compare to growing, shrinking must be conservative a little more,
if the launching thread find other thread are trying to grow ht,
it means the launching thread got old information, it should
stop to shrink.

I think I should used "relativistic agressive".

Thanks,
Lai
