I'm using runit as my primary init on Linux to good effect but have noticed
that it accumulates CPU time even while the system is idle. I suspect that
this is a consequence of runsvdir polling the service directory for changes
and that using inotify would reduce this. This would introduce some
comp

After some more investigation the problem has gone away. I suspect operator
error. Specifically the runsvdir CPU usage was likely caused by a misconfigured
service that was generating frequent readproctitle messages. Oops. Current CPU
time is about 58s over 28 days uptime which seems fine.

Polipo is no longer maintained but overall quite nice. Good support for
pipelining etc.
