velocity in research computing *really* matters

This morning we saw a ticket in RT from Mario Juric who is doing some amazing work on our cluster as a Hubble Fellow over at the Center for Astrophysics. Anyway, so Mario found a problem with our 2.7.1 production version of python.

Mario's request was super simple (stuff we see all the time):
I'm using Python 2.7 installed on Odyssey. Two days ago I've managed to
trace a serious bug it the implementation of one of its components that
caused our codes to (on very rare occasions) produce erroneous results.
The bug has been reported upstream as:

I'd really appreciate if this could be done. Otherwise, we'd have to build
a separate version of Python (and numpy, and scipy, ...) just to get this
fix in.

[any opinions here are all mine, and have absolutely nothing to do with my employer]
