Was just brainstorming, and thinking if multi-threading can be used for
logger as well, just like worker threads?
As a single Bro logger process is becoming big, why not to distribute the
work load across multiple logger processes.
Is it possible to do? and if it impacts manager on the same node?
Anybody tried that?
