As you say, Exim doesn't use O_NONBLOCK on the input file descriptor,
and this problem has not been reported by anybody else. There are
certainly people running Exim under FreeBSD - indeed I tested it on the
exim.org machine.

I don't think there's anything I can do myself, because the problem
doesn't arise on the FreeBSD system to which I have access. Your fix
seems innocuous, but I'm not too keen on just putting it in without
understanding why it should be necessary.
