Please consider that we talk not about reads but about select. 'Select' is
used to indicate that data is available while 'read' used to read it, they
are two different things and behaviour of one thing not related to other.
Currently select indicates that data is available when it really isn't. I
don't ask to fix current read implementation, but select is just unusable
for FIFOs in its current form.
