This is to avoid excessive and inconsistent delays between behaviours that currently need to embed sleeps in other actions (e.g. physics) and other behaviours.
Might need a more sophisticated approach in the long term.
This can be specified on pCampbot.exe by using g in the list of behaviours for the new -behaviours,-b switch
e.g. -b p,g to get both existing physics and grabbing behaviours.
grabbing is primitive, it attempts grabs on random prims whether they're actually signalled as clickable or not.
behaviour is currently primitive overall, behaviours are just executed in a list
