Thanks Dale and Marcelo for your quick report - this is really useful.
The problem seem to be caused due to cgmanager being added as dependency
of systemd in -proposed - this request was clearly explained in LP
#1750013 (not a dup for this, it's another issue with systemd-logind).
During my test I didn't observe such bad behavior of high CPU
utilization - might be some interaction I didn't explore/reproduce. Can
you check please if you're using -backports repo ? If so, then the
cgmanager version installed in your system was 0.39 (the default
version, without -backports repo, is 0.24).
Anyway, the systemd package with cgmanager as dependency was _removed_
from -proposed, so as next step I'll focus in fixing the other LP
without adding cgmanager, and eventually investigate what bad
interaction happened in your case to address it.
