[Numpy-discussion] Vectorize leak fixed (and sage-reported leak fixed as well).

[Travis E. Oliphant]

Hello all,

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 
object arrays.  

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 
memory-conscious NumPy.

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).

Best regards,

-Travis
