Hi pfPeople

To eliminate the pfBuffer::merge() overhead in the Dbase
process, I have recently been trying to manage a pfSwitch
between two processes.

A slow update process builds the scene under the
unselected switch value while the selected switch
value is fed to the graphics pipeline.

The problem: The process working on the unselected
                subgraph causes a SegV when calling
                pfDelete().

I created the process with a regular old fork().
Indigo2 Max Impact, Irix 6.2, Performer 2.1.

Any ideas? I would greatly appreciate any help.
