Hello Jorrit !
Performer collects deletion operations and executes them in an asynchronous
process (DBASE). Calling pfFrame sends the DBASE process for a new frame (if it
is idle).
Deleting objects in a separate (asynchronous) process helps avoiding frame
glitches and doesn't waste any cycles in time-critical processes (APP,CULL,
DRAW).
If you don't fork off a DBASE process, the deletions happen in the APP process
when you call pfFrame.
All in all, you have to call pfFrame in order to delete nodes completely.
