You can allocate memory however you want, as long as you free
it the corresponding way. For example, you can define an
extension type that allocates memory using malloc() in its
__new__ method and frees it using free() in its __dealloc__
method.

You might also like to investigate using the Numeric module.
It's possible to write Pyrex code that operates on the contents
of a Numeric array, and Numeric can take care of the reading
and writing if you want it to.
