Re: Re: RFR: add parallel heap inspection support for jmap histo(G1)(Internet mail)

Dear David,        Thanks a lot!       I have updated the refined code to  http://cr.openjdk.java.net/~lzang/jmap-8214535/8215264/webrev_01/.       IMHO the parallel heap inspection can be extended to all kinds of heap as long as the heap layout can support parallel iteration.       Maybe we can f
