That's pretty much what I figured, but I couldn't find anything
specifically noting that. I just wanted to hear it confirmed from
someone else before I completely wrote this off as a (sort of)
false-positive from chkrootkit.
And yes, as expected, `ps Haux` shows all of them. And `ps aux -L`
shows everything with the parent thread listed.
