| Yeah, this was a good point, as was chris's that EOF is a transient

+---------------

...unless the pipe is really a FIFO, in which case the EOF is (again)
temporary.  (That's how it seemed to work under SVR2, at least.  I would
have preferred that the call block until someone else opened the other end
of the FIFO and wrote to it, though, for the application I was trying to
write with FIFOs.  It made the program work like it was in NDELAY mode.  I
finally ended up using message queues.)
