Workaround: apparently, FreeBSD 8.3 kqueue notifications
break when a dnsblog(8) process loses an accept() race.
This condition is exacerbated because postscreen closes a
postscreen-to-dnsblog connection as soon as it receives the
dnsblog(8) reply, resulting in 100-1000 connection requests
per second. All other multi-server daemons such as anvil
or proxymap have much longer connection lifetimes, ranging
from 5s to 1000s depending on server load. The workaround
is for dnsblog to use the single_server driver instead of
the multi_server driver. This eliminates the race for
accepting a connection. Problem reported by Sahil Tandon.
