I'm unable to build the HOL-ODE-Numerics sessions. Usually, it takes
about ~1 hour of CPU time (0:45 on lxcisa*).
It's been running for almost 2 CPU hours now on lxcisa0 (threads=10) and
over 1:30 CPU hours on my i7 (threads=8). It also doesn't appear to
terminate with threads=2. I'm unsure what's causing it.
Even if it'll terminate eventually (I'll keep it running for a bit
longer), it surely is a sign of a performance degradation.
Last known good state is:
