One way to get malloc() out of the picture would be to provide a variant of hGet that takes an existing, pre-allocated buffer as an argument, so that the user can allocate a ByteString once and re-use it for every single hGet and hPut.
This is already quite easy to do. See unsafeUseAsCStringLen in Data.ByteString.Base, and hGetBuf in System.IO. Is it possible without resorting to an unsafeXXX function? http://www.haskell.org/mailman/listinfo/libraries
