I'm not saying that's a bad idea, but that really is outside the scope of my intentions. 
I'm not really cleaning up rheap as I am fixing one specific problem.

I don't think there's any disagreement here that an integer type (in this case, unsigned 
long) is better than a void * for storing a generic value.  I was really hoping I could 
get a consensus on whether or not *this* patch is good for *our* rheap implementation.
