 Functions for reading/writing actual arrays of bytes in memory.  At the
 moment, `System.Posix` only provides

 {{{
 fdRead :: Fd
- ByteCount -- ^How many bytes to read
- IO (String, ByteCount) -- ^The bytes read, how many bytes were
 read.

 fdWrite :: Fd - String - IO ByteCount
 }}}

 which are not only wrong (`String`?), but too slow for many purposes.

 I propose

 {{{
 Mon May 11 16:21:02 BST 2009  Simon Marlow marlo...@gmail.com
   * add fdReadBuf, fdWriteBuf

   -- | Read data from an 'Fd' into memory.  This is exactly equivalent
   -- to the POSIX @read@ function.
   fdReadBuf :: Fd
 - Ptr Word8-- ^ Memory in which to put the data
 - ByteCount-- ^ Maximum number of bytes to read
 - IO Bytecount -- ^ Number of bytes read (zero for EOF)

   -- | Write data from memory to an 'Fd'.  This is exactly equivalent
   -- to the POSIX @write@ function.
   fdWriteBuf :: Fd
  - Ptr Word8-- ^ Memory containing the data to write
  - ByteCount-- ^ Maximum number of bytes to write
  - IO ByteCount -- ^ Number of bytes written
 }}}

 darcs patches are attached.
