Yes, bge allocates and then releases its property handle during attach. 
But in any case, I don't see how that's related to the problem in hand. 
Property handles are managed completely separately from everything else 
- separate hash, separate access functions. It is not in the way of Nemo 
framework in terms of attaching/detaching or stopping/starting driver 
instances.
