Implement object cleanup mechanism
----------------------------------
Key: SLING-333
URL: https://issues.apache.org/jira/browse/SLING-333
Project: Sling
Issue Type: New Feature
Reporter: Felix Meschberger
In a message on the dev list [1] Bertrand stipulated a cleanup feature along
these lines:
I'm talking about *automatic* cleanup of such objects at the end of a request,
scenario:
1. Object A calls a method M of class C, that creates something that must be
cleaned up (ThreadLocal variable for example)
2. Before returning, Method M registers itself to be called for cleanup at the
end of request processing
3. Object A doesn't have to care about cleanup, it will happen automatically.
This is much more foolproof than requiring A to call cleanup explicitely, hence
my suggestion to implement a general (request-scope for now) cleanup mechanism.
