Aha! I think I do. The answer is that you have "log_arguments" set,
which causes Exim to start logging (i.e. open syslog) before this
descriptor-closing that happens in the daemon. In my test I didn't have
log_arguments set. Closing syslog before closing the descriptors
presumably allows it to reopen then next time it logs something.

I'll install this closelog() call. Thanks for the debugging.
