[GRASS-user] 64 bit Python in GRASS 6.4.2

I already have GRASS installed, and if I recall the application you linked me to is an interface for installing GRASS? What I'm hoping for is upgrading the version of Python to 64 bit that GRASS is using.
When I open GRASS and go to the Python shell it says it's using a 32 bit version of Python 2.7.2.
I know it's a separate installation for ArcGIS to get a 64 bit version of Python installed so I was thinking that GRASS may be the same procedure?

I've been working on a r.cost and r.drain python script that is using very large rasters. I've been running into some memory issues with this script due to the size of the rasters. I read about setting the amount of memory that the map can be stored in with the "percent_memory=xx" argument for r.cost, however the performance of running the script is becoming a problem (it takes too long to run for our goal).
I then started watching the Task Manager and noticed it was peaked out at less ~4 gigs of ram and I realized it's only a 32 bit version of Python installed with GRASS.
My question is: is there a compatible 64 bit version of Python for GRASS 6.4.x, and if so, how does one install it?
Thanks for your help!
