I'm not really participating in this discussion, but this point struck me as
odd. Why should one use Addr rather than (Mutable)ByteArray?
- because Addrs don't move, so you can
safely pass them to foreign imports that
might re-enter Haskell.
why should one use (Mutable)ByteArray?
- because they are cheaper to allocate
and free to garbage collect, and you
don't need to explicitly release the
storage.
So it's not always clear cut.

Hmmm. Posix's read and write (presumably you mean fdRead and fdWrite)
aren't thread-friendly, don't do any buffering, and don't work with Handles.
