Destructors are mainly used to deallocate resources that are not under 
the GC's thumb.  When interfacing with C libraries, for instance, you 
typically get pointers to structs (or whatever) from the library. 
Unless the library itself was coded in D, you nede to free it 
explicitly.  Destructors are the place to do it.
