[Firebird-devel] Releasing of classes derived from IDisposable

   Isn't such trick dangerous?

   I see in manual that "You can explicitly convert a pointer to a class X to a pointer to 
some class Y if X is a base class for Y. A static conversion can be made only under the 
following conditions:
- if an unambiguous conversion exists from Y to X
- if X is not a virtual base class"

   But IDisposable is "a virtual base class", isn't it?..
