SubjectRe: No Bug: accept discards socket options/O_NONBLOCK
I'm going to work around this Linux bug in the next release of djbdns,
just as I've worked around many other Linux bugs in the past. But the
bug is going to continue to bite people.

O_NONBLOCK is not an fd property. It is an ofile property. Two different
fds created by dup() will point to the same O_NONBLOCK bit.

The absence of a non-blocking fd property causes reliability problems,
as discussed in I'd really like to
have ndelay_read() and ndelay_write() syscalls.
