Looks like the HighMem low watermark was hit again (though I've no idea
if that's actually significant).
I kno that people routinely forget to do that, but
at least for purely paranoid reasons you are better
to run all daemons with setrlimit'ed memory size.
At least all daemons which you cannot reasonably
trust to be 100% leak-free and to have bounded
peak memory usage.
Afaik we don't actually implement RLIMIT_RSS.
