I've run out of memory in NeWS a couple of times when I've
been playing with lots of canvases with lots of subcanvases.
Each canvas also has a process looking for events.  I'm wondering
how to make sure that these canvases are garbage collected.

A possible list of things to do to insure that canvases are
garbage collected:

	1.) Remove all references to the canvas in my dictionaries
	2.) Unmap the canvas
	3.) Destroy all processes awaiting events for the canvas

Is this necessary and sufficient?  Can I just unmap a parent canvas
and forget about the children?  Do I need to turn off retained?

I am running 3.4 and 4.0 with NeWS 1.1.
