Comment:

 I noticed the same issue when setting up an OnionPerf instance on Ubuntu.
 It would be nice to find a solution that works for 2.2.1 and 2.4.

 Is there any way that we can avoid calling `g.node` or `g.nodes`? Maybe
 there's a function for that that hasn't changed its name between 2.2.1 and
 2.4? Or maybe we can specify `socksproxy` when adding the node in the
 first place? (It's too late for me to try this out today, but I wanted to
 leave this idea here just in case somebody wants to pick it up.)
