Btw. storablevector supports 'zip' using
http://hackage.haskell.org/package/storable-tuple
but you may also use 'zipWith' with an atomar result type for testing.
However, I have noticed that the instances in storable-tuple are not quite
efficient. They are implemented with storable-record, which is elegant,
but apparently too hard to compile efficiently for GHC. Storable-record
computes the offsets for members of a record automatically according to
their aligment constraints. But GHC seems not to realize, that the offsets
are constants.
