[logback-user] getting logback to scale on multitenant app

[Jamie]

To follow up: I examined the Logback source code in the repo. 
Specifically, the class AsyncAppenderBase 
<https://github.com/qos-ch/logback/blob/master/logback-core/src/main/java/ch/qos/logback/core/AsyncAppenderBase.java>. 
It appears as if this is a design issue.  To get it to work the way we 
want, Logback code would need to be refactored. Each appender is 
assigned its own worker thread. The worker thread is started when the 
appender is started. I guess the designers of logback hadn't anticipated 
a scenario where many appenders would be used.

public void start() {
         ..
         worker.setDaemon(true);
         worker.setName("AsyncAppender-Worker-" + getName());
         super.start();
         worker.start();
  }

Cheers
Jamie
