Comment (by duncan):

 One problem with this patch is that it makes the type of hPutNonBlocking
 different for GHC vs non-GHC. It's not clear to me what the right API
 should be either. I presume it currently returns the number of bytes
 written, and you need to check that to see if the write completed
 sucessfully or if there's more left to write. Perhaps the right api would
 be more like:

 hPutNonBlocking :: Handle -> ByteString -> IO (Maybe ByteString)

 So if it returns Nothing you know it wrote it all, otherwise it returns
 the remainder of the buffer that it did not manage to write (which may be
 the whole original input or some tail of it).
