Subject: efficient access to a large int32 array

I have a file that is a dump of a large array of 32-bit unsigned ints
(bitvectors actually). All I need is to load this into memory and have
fast, efficient access to the array members, and a few bitmasking
operations - the array will never be written to, and ideally should
not need to be bounds-checked. Should I be looking at something like
mmap or narray to do this, or would I be better served by a custom C
extension?
