Ack, noted. Fortunately the machine doesn't care too much. I let them build with MAKE_JOBS etc and let it grind at >100 load avg for a while. I even priority boost to get them to build as soon as possible to unblock downstream builds.

I'm more concerned at just how much downstream they block.

Is there anything in particular that is giving you trouble? I've mainly used it to bridge epair interfaces for vnet jails to ethernet.
