That is weird. However, you still have a bunch of tag handler instances,
I see...

So you have 60k in SetPropertyTag objects? If you use them a lot
(without pooling), then you'll get a lot of them on the heap at any
given time. Can you observe that the number keeps going up, and never
goes down?

Not necessarily. It might just be that they are taking a while to get
GC'd. Again, what do you observe over time?

Okay, that's good.
