I haven't experienced this issue on recent 14.09 images. However, now I
have a proces called "init" (not the one with PID 1) that takes 200 megs
of RAM and constantly about 15% of CPU:

This time, I have strace installed and recorded a few seconds of its
output.
Do you think this is related, or should I open a new bug for this?

Title:
initctl eating cpu on mako #181
Status in “upstart” package in Ubuntu:
Expired
Bug description:
On Ubuntu image #181 on mako my phone is hot. I checked top and found
initctl eating 96% of the cpu..
This may be related to bug 1281057 as my phone refuses to lock.
Unfortunately I couldn't get the bug report done on the phone because
the battery died (unsurprisingly) mid way through reporting it.
Managed to get this output from top though.
