 * @brief The static (global) resoures of all POA's.
 *
 * This class is used by the POA to store the resources global to
 * all POA's.  All instance variables that would have been
 * declared "static" in TAO_Regular_POA, should be declared in this class
 * to avoid the "static initialization order fiasco" as described in
 * http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.11.
 * Briefly, this is the problem that occurs if any static initializers
 * in any other code call into set static members of TAO_Regular_POA.
 * Since the order in which these initializers execute is unspecified,
 * uninitialized members can be accessed.
