Please describe the problem:
When I open System Monitor and sort processes by memory usage, new entries are placed in the middle of the list or at the top.  An example is the ping processes spawned by Azureus.  These 612 or 616 KiB processes are placed up with processes using 100 MiB or more, not where they belong.  On refresh I think they are sorted correctly, but are replaced by more.

Steps to reproduce:
1. Run Azureus, possibly with the Ono plugin installed.
2. Open System Monitor
3. Sort by memory usage (other categories will have the same issue)


Actual results:
Ping commands using little memory appear towards the top of the list.

Expected results:
Ping commands using little memory should be placed at the bottom of the list, sorted accordingly.

Does this happen every time?
Yes, every time Azureus is running.  I haven't tried reproducing it without Azureus with other programs.
