network-manager using 70%+ CPU on Nexus 4
Status in network-manager package in Ubuntu:
Incomplete
Status in network-manager source package in Saucy:
Won't Fix
Bug description:
This morning after moving around between multiple buildings / wireless
domains, NM is now using 70%+ CPU on my Nexus 4 (mako). I noticed
this because the UI was being very slow to respond.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

strace doesn't show much interesting, so most of the CPU time seems to
be spent in userspace.
