Event handling in multinode data processing networks, in which data structures are shared between nodes and are subject to concurrent requests for access, is facilitated through the use of a separate small data structure which permits an event handler to hand off the task of accessing the data structure to an event handler which is already accessing data from the same data structure. The reducing sugars are typically selected from fructose and xylose. The overlay has an overlay front side with adornment, coloration, art work, or embossment, and also an overlay rear side which is intended to be attached to a chain link. The delivery device may be inserted through the passageway created by the access device and may be used to deliver the pressure-attenuating device to the anatomical structure. A coil leading guide is prepared for inserting the densely spiraled coil through the holes in the sheets. Embodiments include using an MIH proxy entity, MIH capable network controller, and an MIH server.
