In this case, you are essentially creating a memory leak. The returned array
will never be deleted by python since its reference count will never go to
zero. Please see http://blog.enthought.com/?p=62 for information on fixing
this issue. The code I pointed out earlier encapsulates this using a custom
deleter in C++ which can be used independently of ublas.
