Hello,

There are many basic ways to control processes, including capabilities,
cgroups and resource limits. However, there are far fewer ways to find out
useful values for the limits, except blind trial and error.

This patch series attempts to fix that by giving at least a nice starting
point from the highwater mark values of the resources in question.
I looked where each limit is checked and added a call to update the mark
nearby.
And how is that useful? Setting things to the high watermark is
basically the same as not setting the limit at all.
