  So there's a requirement to handle HUP.  I don't see why.

  How about a requirement to dynamically update the running
configuration?  That could be done via re-exec on HUP, or by the crazy
SQL scheme I talked about.

  I don't understand the fixation on HUP.  I don't like SQL, but if I
can use an SQL client to edit *every* configuration parameter in a
running server, I don't see why HUP would *ever* be necessary.

  Recent versions of OpenLDAP support an "dn=config", or something like
that.  It means any configuration parameter can be dynamically changed,
meaning you *never* have to HUP the server.
