Before I go to the details below could you, please, explain why do we need a

when maxfilesize is reached, the file is renamed with numbered suffix, and new
file is created to use. so there can be IncrementalHisto.dump.0 and
IncrementalHisto.dump.1 etc for large heap.

Subject: 答复: [RFR]8215623: Add incremental dump for jmap histo
Dear Paul,
Thanks for your review, I agree your suggestion to make incremental
general. and
I think the incremental file is better to be different with the file or
the "out"
same folder,
if "filename" not specified, it will dump to current dir. And if "chunkcount"
is 0 or max_int, or "maxfilesize" is 0, the incremental dump will be disabled.
