None of that is relevant to setting the nodelay option.  If you actually
read through the series you'd say that whenever there was non-trivial
logic it is shared with getopt.  However sharing just for purpose of
sharing doesn't make sense, so where the kernel API ended up just
setting a flag after taking the sock lock I did not opt for it.
