Re: NT port of slapd (ITS#869)

The simplest way to avoid this problem is to have the main function of slapd
set a flag to indicate that it has run and have the encapsulating service
function use this to avoid running main a second time.  Or the complete
"only-run-me-once" code could be kept in main.c.  Neither is elegant.

I am happy to prepare the patch for this if one of the above solutions is
acceptable.
