Hi Paul,

Is this only occuring when you've been logged into your machine for a 
while? I'm monitoring this on SIPB's Natty box (with zwgc running and 
subscribed to a few classes) and it looks like we're getting only about 
50-60 kB leaked per minute, which comes out to about 80 MB a day. While 
distasteful, it doesn't seem like it's actually an issue, especially in 
the cluster environment where users shouldn't be logged in for days at a 
time.

The bug report you linked to, and a few linked from there, implicate 
indicator-multiload and possibly other indicator-* packages in greatly 
exacerbating the memory leak. Are you running any of those? Without them, 
it seems like Unity is still leaky but manageable.
