The logging implementation stores the logger in a map.  However, when =
you call getLogger ClassLoaderContextSelector will have to locate the =
ClassLoader for the class loading the Logger. This can be fairly =
expensive. If you are using a different ContextSelector it might work =
better. Or you can create a Map of the Loggers yourself.
