docker: Event polling disrupts power saving

[docker]

Package: docker
Version: 1.4-4
Severity: important
Tags: patch


docker is doing event polling using a 0.5 seconds interval. This
disrupts power saving, making the processor wake up (see powertop).

Attached is a patch to avoid polling, making docker much more
power-saving-friendly.

Feel free to send the patch to upstream, it's Public Domain to avoid any
problems with licensing =)
