Let me follow up with this.   I've changed back dtype.hasobject so that 
it returns a Python boolean object.  Thus comparisons to 1 should work 
fine.  Under the covers it is

(dtype->hasobject & NPY_ITEM_HASOBJECT) == NPY_ITEM_HASOBJECT)

There is a new attribute (flags) that contains all the flags in the 
hasobject variable.
