Comment:

 I have decided to add the function with this type:
 {{{
 hPutNonBlocking :: Handle -> ByteString -> IO ByteString
 }}}
 That is, it returns the unwritten tail, if any. This generalised better to
 the lazy bytestring case. In the lazy bytestring case, using the number of
 bytes written would mean that any correct program would necessarily have a
 space leak.

 This change is now in the upstream darcs repo and will be in
 bytestring-0.9.2.0 which will be released soonish.
