Maybe someone should run it through a memory profiler to be sure.
But, sounds pretty good.  I think we need to make sure that tapestry's
class pool doesn't maintain a hard reference to its generated classes.
But, if the classloader is thrown away, that might just do it.

The "PermGen" problem is elusive, but I think it will be less common
in T5. It was caused by the shear volume of classes generated (every
component gets a subclass) multiplied by a full reload on every
request.

T5 is stingier; it only enhances classes once, until some component
class changes. Then it throws away all the page instances and the
class loader used to enhance them.

Now, I can't be certain this fully clears up PermGen, since there's
always the question about whether the ClassLoader and all of its
classes is being properly relcaimed by the GC (I believe Tapestry is
doing its part), but at the very least, we're on the right track.
