open2? Has anyone tested this with spamd? The reason I ask is that I
recently wrote a networking daemon in Perl that used open3() while doing
the canonical close() on STDOUT, STDIN, and STDERR. I couldn't get it to
work until I redirected those file handles to /dev/null rather than
closing them. Probably something to do with the way open3() handles
close-on-exec (FD_CLOEXEC) for filehandles other than those. I don't
know if the current code handles this correctly or even does the
close-on-exec, but it's a potential gotcha.
