This reminds me the unfortunate (and much needed) lack of an unified way to send/receive out-of-band data to/from a regular fd.
Something like: oob = fd_open(fd, channel, flags); write(oob, ...) read(oob, ....) close(oob);
Don't you think it's time to introduce it and to start to avoid the proliferation of different tricky ways to do the same things?
