I like these functions.

I also want to mention buffer operations, following in the tradition of 
hPutBuf and hGetBuf (which improved performance in the 
haskell-web-server...), perhaps:

sendBuf :: Socket -> UArray Int Word8 -> Int -> SockAddr -> IO Int
recvBuf :: Socket -> UArray Int Word8 -> Int -> IO (Int,SockAddr)

...which would allow explicit memory reuse.  Incidentally I was always 
disappointed at not being able to use explicitly buffered Socket IO in 
Windows (buffered ops already availible in most Unix-like systems because of 
the socket<->handle mapping).

Yrs, WG.
