[pLog-svn] Some programming questions?

[Oscar Renalias]

Are we really sure that this would save any memory?

As far as I know, PHP's garbage collector will free the memory used by  
an object as soon as the object is out of the current execution scope.  
This means that if I create an object of type User via the "new"  
operator in my own function, its memory will be freed as soon as I  
leave my function. However, if I use a static reference to that  
object, its memory will not be freed until the request is over.

Is this really what we want to do in all cases?
