I could not figure out how this could be expressed via Ruby bindings.  
This function is called when object is freed, but when it happens is  
controlled by GC.

For example, KDE Ruby binding are using dispose() method paradigm to  
solve this kind of problem:


Should we add one to Domain class?


P.S. I think the Python bindings have the same problem, virDomainPtr()  
is called from __del__() there.
