[vtkusers] Deleting vtkActor takes long

[Clinton Stimpson]

I sprinkle some of these around in my code.

vtkGarbageCollector::DeferredCollectionPush();
... delete code ...
vtkGarbageCollector::DeferredCollectionPop();

It would be nice if this problem were fixed.
I wonder if my problem is related to the cross referencing that happens in 
painter chains.
