How to make emitting application wait until all buffered log data has been sent to beagle?

[vorburger]

I've noticed a small problem when wanting to use Beagle to see the logs of short running unit tests:

The JVM of the test being run may quit so fast that nothing ever shows up in Beagle.

Do you think there may be a way to make logback cause the JVM exit to wait until all buffered log data has been sent to beagle? Perhaps using a non-daemon background thread kind of thing? If you can point into the right direction, maybe I can come up with something.
