This is documented behaviour. You can't open a FIFO in read mode
until a writer has opened the FIFO - instead the open(2) syscall will
block. You can pass the O_NONBLOCK flag to open, in which case the
open call will not block. Or you can open for read and write (because
you yourself are then supplying a writer).
Some more details here:
