After cursory tests:
 * it appears that the proper python command line is
'#!/usr/bin/python2.5 -OO'; using 'env' or separating the '-O' options
doesn't work.
 * when you do this, /usr/lib/python2.5/site-packages/numpy/ma/core.py
raises an exception, since it does a '+=' on its __doc__, and __doc__
is None.  Commenting out line 3256 fixes this.  I've attempted to
report this bug upstream, but numpy does not appear to have any bug
tracker. =(

Other than that, seems to work.  I could still use some help doing
some measurements to quantify the improvement (if any), since most of
my day today will probably be spent on build-related issues.
