we use here a cdb database for white/black listing that is rebuilt every
5 minutes from a mysql database (with more than 4 million ip addresses),
in our case the cdb read speed compensates the databse rebuild every 5
minutes. Of course this maybe even better using some dbm like database
but we don't have tried it yet. For other purposes where data is updated
from time to time is even better (username/passwords, etc ...)

daemontools is not need at all to have cdbmake working.
