That could work, but it's a bit of a stretch.
One of the problems here is you would have multiple DumpableObjects out
there unnecessarily. And if you want to change the location of the dump
file, for instance, you need to change it in all the objects. Of
course, you could use static members for the location. But I think it's
unnecessary overhead.
