Much thanks is deserved by the people who have been chasing down and
fixing reference count problems in NumPy. Two of them are related to
So, if you have been having memory leak problems with object arrays
(vectorize uses object arrays, BTW), you should try out the latest SVN
of NumPy to see if they fix your problems. Hopefully, NumPy 1.0.5 will
come out sometime next week so that everybody can enjoy a more
The vectorize-related leak was a particularly silly one which led to
casting for simple cases actually doing more work instead of less (this
led inexorably to leaks whenever object arrays were cast to other types).
