What I need to do is remove a subgraph of my pfScene, update it asynchronously
in the DBASE process, and then give it back to the APP process later on.
Removing the subgraph is easy--one call to removeChild() in the APP process
and it's done.
However, when I then go to modify the subgraph in the DBASE process, the pfBuffer
mechanism gets in my way. The subgraph is still in the APP pfBuffer, and
there doesn't seem to be a good, inexpensive way to move a large subgraph
from one pfBuffer to another.
Does anyone know a way to disable pfBuffers (since I can guarantee that the
nodes I modify will not be used during that time by the APP process), or some
other solution to this problem?

ps the pfBuffer man page mentions that setScope() can be used to move
objects out of the APP pfBuffer for asynchronous updating, but it
seems it setScope() would need to be applied recursively to every
node in my (very large) subgraph! That kind of defeats the purpose,
especially if I have to call setScope(node,false) from the APP process.
(which I assume I do...)
