Note that the engine does not guarantee you any particular value of the 
refcount. Passing parameters around, accessing variables, etc. may 
change the refcount. One thing the engine guarantees you is that once no 
links to the variable exist it would be destroyed (which may not happen 
immediately after you do unset, for example, but probably would happen 
"soon"). So actually figuring out if the object is referenced by any 
other place could prove non-trivial, depending on the application 
structure.
