Comment 2 for bug 785828

Test case:
- get indicator-multiload from: https://launchpad.net/~indicator-multiload/+archive/daily/+sourcepub/1880139/+listing-archive-extra
- launch it from Applications->System Tools->System Load Indicator
- indicator->preferences->refresh interval to 50ms
- quit the indicator (important!)
- launch it again from Applications->System Tools->System Load Indicator
- monitor its memory use with "watch 'ps aux|grep multiload$'"

- with ubuntu3: increase in memory use of 8kB/2s
- with ubuntu4: no increase in memory use
