[logback-user] Limiting events to one thread in email

Thanks Ceki,

I had a look at this and I'm not too sure if it is the best approach or actually feasible... Allow me to give a few more details.

1) We're using the AsyncAppender as per 

(by the way, it would be great to include this in an official release!)

2) The processing can happen from a JMS Message or an RMI call, or a GUI event... there is no real single entry point where I would be able to put a value in MDC...

Would a Cyclic Buffer per thread name in each event be a more appropriate approach?  What do you think?
I'm not sure we could use Thread.currentThread().getName()
to distinguish each caller as the AsyncAppender would be using their own thread and not the one that actually originated the event... In which case, the interface get() on the CyclicBuffer is not suitable since I would have no way to give it the name of the thread that called the Error...

Your opinion/suggestion/solution are appreciated,
