Before, jmap -histo accepts a parallel=<n> option to indicate the number of parallel threads, which exposes too much details to user and makes spec hard to be clear and not to be ambiguous.
We think it's better to enable parallel heap inspection by default and adjust jmap -histo to accept a "noparallel" option to disable it, rather than give user too much control/details which is hard to specified.
