Comment 14 for bug 1173915

Happens on Ubuntu 16.10 (fresh install, Compiz fallback session) after a few hours of uptime.
htop reports 100% usage of one CPU for the command

/sbin/initctl emit indicator-services-start

which goes on indefinitely. Tracing (with only this initctl process around) yields similar to #5

$ sudo strace -p `pidof initctl`
poll([{fd=3, events=POLLIN}], 1, -1) = 1 ([{fd=3, revents=POLLIN}])
[endless repeat]

/var/log/upstart is empty and dmesg/kern.log/syslog don't help.

The random battery drain is annoying (especially during presentations), and apt purging upstart depends on a little too much for comfort.

Suggestions?
