Martin Schreiber recently mentioned in another Interface discussion that
there is a very good reason he doesn’t use COM style interfaces…
Reference Counting!

Stick with CORBA style interfaces and things work much simpler. I have
to agree. I’ve used CORBA style interfaces for years with great success
and no memory leaks. You get all the benefits of Interfaces, but without
the Reference Counting troubles and complexities. If you really are
writing COM (Windows specific) applications, then fine — otherwise use
CORBA style interfaces.

Just my 2¢ worth.
