[vtkusers] Very important discovery\mistake !

[bryan cole]

In the past, I've forced sections of pipeline to delete by individually
setting the inputs and output of *each* filter to NULL (i.e.
disconnecting them all), and removing and other python references to
them (no necessary for C++ presumably). 

As far as I know, a filter is only deleted if it has no connections to
any other filters/objects. I'm not sure if VTK is smart enough to detect
"isolated" sections of pipline for deletion.
