I did a lot of searching and almost all of it relates to using cgroups
for services, like mysql or something.  I haven't found anything that
explains how to do it for a program started by a user.  It may be doable
but I've yet to find it. 

It's rare so I may just have to close Firefox and such before I nap or
leave for a while.  Avoid the problem that way.
