That may be related to syslog (although it's still hard to believe
that it takes 5-15 minutes). If you use syslog as an output channel
of named logs and (if so) disable it, does that make any change?
Also, what if you start named with the -g command line option? Is
there any obvious bottleneck before you see "running"?
