I agree we need support for this sort of cross-thread context
information....properties which are inheritable through the logger
hierarchy may fit the bill..I haven't looked into implementation
details, but here's an example:

If you got the "org.apache.log4j" logger and called
'setProperty("someprop", "someval"), then all loggers under
org.apache.log4j would also have the property (you would also need
support for removeProperty("someprop")).  The property would be
overridden if a closer ancestor set the property (if
org.apache.log4j.net set the same property).

Opinions dev folks?

Log4j gurus,

Does log4j have support for MDC/NDC across other contexts than threads?
If not, is it any plans to implement this? For the time being I find my
self having to prefix log messages with context sensitive information,
and it doesn't really "feel" right at all.

Any suggestions for a MDC/NDC framework allowing arbitrary contexts
would be much appreciated, and also how to incorporate it into
PatternLayout etc.
