You can put them on different "queues" (pipes, TCP/UDP-Sockets, ...)
based on priority. This will allow syslog messages with higher priority
to "overtake" messages with lower priority, but only if no queue
actually fills up. If syslog-ng blocks trying to write on any queue it
will block as a whole (using TCP for high-priority queues and UDP for
low-priority queues might mitigate this).
