[pymvpa] Mac memory issues w/ large datasets

[Yaroslav Halchenko]

well... everything, sure thing depends on how much RAM you have in
general ;-)  otherwise I am not sure what is the exact 'issue' ;)

and regardless either mask was applied, you better load with brain mask
just to avoid wasting memory/cpu on searchlighting outside (although,
then you would fail to discover the throat ventral pathway as it was
done in 0.5 tutorials ;))
