2.  If one opens the pipe for reading, and there is not a writter at
       the other end:  Doing a select for read will return true, but
       when the read is actually done it will block as there really
       isn't any data there.

If there are no writers, it will halt inside fifo_open() waiting for one,
unless you have non-blocking mode set.  As far as I can tell, the rest of
the code does the correct thing.

Can you send a specific, small piece of code which demonstrates what you
think is a bug?
