Thanks!

I this done now?  (I saw a bunch of checkins to logging stuff.)

You fixed these now.

(I'm not real excited about the following to subjects, do what you see
fit.)

(Sounds find to me.)

(Ditto.)

Yes, you can raise an exception and return.  This is a bit weird
(there's no return value) but AFAIK it is documented that a module
init function can raise an exception and return to indicate failure.

I have a tentative fix for this (use PyNumber_Check() in
default_3way_compare() and augment PyNumber_Check() to test whether
the type defines nb_int).  Can you check this on AIX?  [*]

Yes.
