I also think so.

Your patch set and in particular ChangeLog looks very elegant to
me. So, I am not going to repost further patch set.

On the other hand, I'd like to report that I've attempted to create a
coredump using gcore sub-command following the way you suggested
previously, i.e. increasing threads.

For this, I've need:
    * prepare at leat 700GB strage (on X64 and IA64 arch),
    * set kernel.threads-max to a reasonably large value, and
    * one and a bit hours for the dumping process.

Thanks.
