Ah, OK. Indeed that's much faster this way.

Yeah. I can see how this messes up with the calculation of the
conditions, which is enough from my perspective, even if we don't have
any sanity checks in 818fefd8fd originally.

It's been mentioned recently that we are not good at detecting crashes
in the TAP tests. I am wondering if we should check the status of the
node in the most popular routines of Cluster.pm and die hard, as one
way to make the tests more responsive.. A topic for a different
thread, for sure.
