Sorry for the late reply (holidays and traveling). That would
seem reasonable to me, but patches in the python/ subdir have
traditionally been Tom and Doug's territory.

My suggestion is to modify your comment about AIX to include
the issue you've been describing in this email chain, to make it
easier to remember why the workaround should not be applied on
AIX, and then resubmit on gdb-patches, with Doug Evans in Cc:.
