I haven't been following closely, so I don't know what version of Java 
you're working with, but a web search for "java garbage collection 
tuning" usually gives lots of good hits.

<http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html#available_collectors>

You probably want the parallel GC or the concurrent GC.  And no, you do 
not create a new thread or "juggle memory," you configure it externally 
to your application.

Also, take a look at the System.gc() call, but DON'T USE THAT unless 
you're sure you need it.  The garbage collector is probably smarter than 
you are about when and how to collect unused memory, frankly.
