Detailed Description

Provides fast tiered lookup for data structures used to process NCX messages.

The data structures 'pointed to' by these registry entries are not managed in this module. Deleting a registry entry will not delete the 'pointed to' data structure.

   Entry types

   NS:
     Namespace to Module Lookup
     Key: namespace URI
     Data: module name and back pointer

   FD:
     File Desscriptor ID to Session Control Block Ptr
     Key: File Descriptor Index
     Data: Session Ptr attached to that FD
