Severity: important
Control: affects -1 s6
Dear Maintainer,
When calling open(fifo_fd, O_WRONLY | O_NONBLOCK) on an fifo file, which has
no reader, it should return ENXIO. But on Hurd, it returns EIEIO.
This causes s6 failed to start[1], as it expects an ENXIO.
The behaviour should be consistent with

> [ENXIO]
> O_NONBLOCK is set, the named file is a FIFO, O_WRONLY is set,
> and no process has the file open for reading.
