Turns out that this is Sun's code (surprise surprise!). It appears to be something
related to text component cursor blinking. Here is the OptimizeIt output:

Class name                                                            	Instance count	Difference	
----------------------------------------------------------------------	--------------	----------	
javax.swing.SystemEventQueueUtilities$RunnableEvent                   	76            	+ 69      	
java.awt.event.ActionEvent                                            	75            	+ 69      	
java.awt.EventQueueItem                                               	75            	+ 69      	

These numbers climb in sync at a rate of about 2 or 3 per second (kinda like a "blink rate").
If I GC they collect just fine.

I hate the idea of adding yet another thread to periodically GC, but this leak will simply
eat whatever memory the JVM will give it...
