Re: RFR (round 1), JDK-8214259: Implementation: JEP 189: Shenandoah: A Low-Pause Garbage Collector

[Zhengyu Gu]

Hi Kim,


     - taskqueue.hpp has some small adjustments to enable subclassing

Why this change instead of JDK-8204947?  As the description from that RFE says:
"The ShenandoahTaskTerminator from the Shenandoah project is a much better 
implementation of a task terminator.”

We were busy on preparing Shenandoah for upstreaming, this did take a 
back seat.

I am going to start to work on moving ShenandoahTaskTerminator to share 
tomorrow, but it should not hold up the review.

Thanks,
