The Daemontools look very handy!  I run qmail under them but hadn't paid 
enough attention.

If ns-slapd is started with -d<error level> it will not fork-and-exit 
and it logs errors to stdout.  That's how to launch ns-slapd in debugger 
and avoid having to follow children.  You can use the regular 
start-slapd script to pass arguments, like "start-slapd -d0" for normal 
log level.
