BTW I'm working with Roman Leshchinskiy to create the
vector-bytestring package which provides:
type ByteString = Data.Vector.Storable.Vector Word8
and exports the same API as the bytestring package (no support for
lazy bytestrings yet)

A storable vector still uses a ForeignPtr but maybe this will make the
switch to unboxed Vectors (which use ByteArray#) easier.

Expect some code to be up somewhere next week.
