Well, it seemed to be something in use out in Solaris-land (cf also https://blogs.oracle.com/stw/entry/guidelines_on_zones_with_shared -- it's a parameter in a config file or something, it looks like), so I went ahead and used it. I'm not in love with it or anything.

I can remove it from the inline text, but I'd like to at least have it in a parenthetical so people ctrl-F-ing the page will be able to find it.
