Not a bad script for testing long term effects.  I've found the 
problem.  There were two:  a scalar array object was not being incref'd 
when retrieved from a.dtype.  Also, and more relevevant to this issue 
was that .put for OBJECT arrays was not holding on to a reference to the 
objects placed in the array (nor was it DECREF'ing the current contents).

This bug is in Numeric as well, but was never discovered -- the put and 
putmask code came directly from Numeric.
