title: is memory leak? why java.lang.ref.Finalizer eat so much memory
body: <p>I ran a heap dump on my program.  When I opened it in the memory analyzer tool, I found that the <code>java.lang.ref.Finalizer</code> for <code>org.logicalcobwebs.proxool.ProxyStatement</code> was taking up a lot of memory.  Why is this so?</p>
