/** XXX/REVISIT:
 * We do not want to look for a servant in the POA/ServantManager case,
 * but we could in most other cases.  The OA could have a method that
 * returns true if the servant MAY exist, and false only if the servant
 * definitely DOES NOT exist.
 *
 * XXX/REVISIT:
 * We may wish to indicate OBJECT_HERE by some mechanism other than
 * returning a null result.
 *
 * Called from ORB.locate when a LocateRequest arrives.
 * Result is not always absolutely correct: may indicate OBJECT_HERE
 * for non-existent objects, which is resolved on invocation.  This
 * "bug" is unavoidable, since in general the object may be destroyed
 * between a locate and a request.  Note that this only checks that
 * the appropriate ObjectAdapter is available, not that the servant
 * actually exists.
 * Need to signal one of OBJECT_HERE, OBJECT_FORWARD, OBJECT_NOT_EXIST.
 * @return Result is null if object is (possibly) implemented here, otherwise
 * an IOR indicating objref to forward the request to.
 * @exception OBJECT_NOT_EXIST is thrown if we know the object does not
 * exist here, and we are not forwarding.
