And we will have access to this when? Please oh please :) I'm supposed to do 
some C/Fortran/Python benchmarking to convince my boss that we _can_ use 
python for most of our new code (fast algorithms development) --at least for 
the prototyping and the higher level logic, of course. I'm kind of holding 
back and keeping under his radar b/c I'd like to have access to these 
improvements before I do the testing. I _really_ don't want to have to end up 
writing fortran code.

So you would have at least one eternally grateful user out there if this makes 
it into the wild.

cheers,

f.
