Results in:

after close
Exiting BlockFile::this
after second open
Segmentation fault

I could post all the code.  It's only 146 lines.  But perhaps this is 
enough?

So after the discussion I decided that it appeared to make BlockFile 
into a scope class.  I did, removing all destructors and delete 
operations.  The new main method was:
void  main()
{
   {  scope BlockFile   bf;
      bf =  new   BlockFile ("test.bf", 4096);
      writefln ("before close");
   }
   {
      writefln ("after close");
      scope BlockFile   cf =  new   BlockFile ("test.bf", 4096);
      writefln ("after second open");
      writefln ("after writefln");
   }
}
Yielding:
Exiting BlockFile::this
before close
after close
Exiting BlockFile::this
after second open
after writefln

Apparently this can't be handled with garbage collection.
