We are having some troubles doing multiprocessing with Performer.

I'm wondering if the problem is intersections.

1) Can pfChanPick and pfSegsIsectNode be called from
a node DRAW call back (pre and post)?

2) Can pfChanPick and pfSegsIsectNode be called from
a node CULL call back (pre and post)?

3) What does the Performer manual mean when it says that
   pfSegsIsectNode can only be called from the APP or ISECT
   processes? I'm not sure when and where the ISECT process
   gets called. Does it get called during the cull or draw cull
   processes?
