Thanks! The patch itself looks good, but we would prefer
to have a complete author name. Is OK to change the
author identification to "Satoshi Kinoshito <>"?

Also, I would like more information in the commit message,
for instance like this:

    system_info(procs): Fix the value for "OldHeap unused"

    The value for "OldHeap unused" in the output of
    erlang:system_info(procs) and in crash dumps, was incorrectly
    calculated as the size of the entire old heap.

If you approve the changes above, I can do the changes for you.
You don't have to re-submit the patch.
