 Read geometry into Performer structures
 Rebuild each geoset with the GeoBuilder
 Free the old geoset
 Write the new geometry
 pfDelete() the hierarchy

Everything is allocated with pfNew* or pfMalloc (geoset arrays).
We got what looks to be a massive core leak, so we tried the
following:

 Read geometry into Performer structures
 Write geometry back out
 pfDelete() the hierarchy

And we still have massive core leaks.
So we decided to try deleting the hierarchy ourselves, thinking that
perhaps geosets arrays were being leaked. Here we explicitly
pfFree()'ed all the geoset arrays, and pfDelete()'ed all the pfNodes.
And still have massive core leak problems.

Has anyone else had similar problems and managed to solve them?

-thanks
