notify-osd keeps on writing to .cache/notify-osd.log and waking up my drive

Bug Description

notify-osd append each notify message to a log in .cache/notify-osd.log. Looking at the code I suspect this is for debugging purposes only, however, I don't seem to have debug turned on and it is still appending data to the log. I have examined this under the current Oneiric installation (with the current updates) and also today's Precise ISO image (15th Dec 2011).

This is problematic for several reasons:

1. I believe the logging is for debugging purposes only, yet it seems to be enabled and I'm using a standard release image

2. Each notify-osd messages causes writes to the log which causes extra unwanted Hard Disk Drive (HDD) activity. On an idle machine running on battery power this contributes to drive wakeup/write/power-down cycles which wastes power and reduces battery life.

3. Unnecessary writes to this debug log causes unnecessary HDD spinup/down cycles which reduces the lifetime of spinning media as well as for SSDs

4. On busy feeds (e.g. twitter, facebook etc) the extra logging overhead and wasteful.

Since this log seems only useful for debug purposes it should be inhibited as default.
