Hmm, RawIO.read looks ok:

-- | Read up to the specified number of bytes, returning the number
-- of bytes actually read.  This function should only block if there
-- is no data available.  If there is not enough data available,
-- then the function should just return the available data. A return
-- value of zero indicates that the end of the data stream (e.g. end
-- of file) has been reached.

that seems pretty clear to me.  No?

I'll expand the documentation for fillReadBuffer.
