Yes, that's what it means. Really I wanted to ban ebuilds from spawning
any process that lasts beyond the scope of the phase function, but
unfortunately some ebuilds do naughty things with init scripts, so
we had to make do with things that query package manager internals...

I seem to recall this being discussed on gentoo-dev along with the
parallelisation stuff, although I can't seem to find an archives link.
