/**
 * Thin layer around an AbstractFilter. Takes care about being started and
 * having a target when it should handle a call.
 * 
 * Concurrency note: instances of this class or its subclasses can be invoked by
 * several threads at the same time and therefore must be thread-safe. You
 * should be especially careful when storing state in member variables.
