I didn't notice this before.  I think this should use the breakpoint's
arch and language.

Phil> +  if (PyObject_HasAttrString (py_bp, method))

Since we're now overloading the "condition" member, what happens if the
user sets a condition on the breakpoint?

I think we may need an additional check here, to see if the "condition"
member is a callable object.
