Description
It turns out that there is a memory leak in LegacyOutputTracker.
To duplicate:
Open Organ Of Corti
Use Delete Axis plugin to delete C axis
close window
If you run the Eclipse Memory Analyzer you can see the event dispatcher keeps a hold of a CompositeImage.
Note that if you remove ThreadLocal variables from LegacyOutputTracker this error goes away. But this would limit us to running only one legacy plugin at a time. Must think how best to track legacy outputs.

"My other fixes" refers to b72c24756c777ff866fe434ac0230107a0fc1fed
Note that this leak is ever growing. If you run this sequence of commands over and over you lose a couple megabytes of ram each time.
