        Not exactly a great description I know :-) I'll get around to

        As for the value, I believe that it is only the current process
usage and does not include the terminated children.

        The value you are after is not to my knowledge tracked by Squid.
It is possible to add it if there are no objections and no reasons that it
is not already there, like OS bugs or incompatibility.
