/*
* NCPs are collections of NCUs. At the moment there is one NCP in the system
* and its expected there will never be many. There is a lock on the NCP which
* must be obtained to add or remove anything from the NCP.
*
* NCUs are also kept in a uu list for easy walking. Each NCU has a lock which
* is used to protect manipulation of its contents. One of its members is a
* reference count which is initialized to 1 when its placed on the NCP. As
* references are passed around that should be manipulated as necessary
* (helper functions YYY provided). It is removed from the NCP by
* ncu_destroy() but the memory containing it is not returned to the free pool
* until the reference count falls to 0.
*
* As we add
* more complex system objects their relationship becomes more complex. That
* is represented by the links within the NCUs. Reference counts should be
* used to maintain the consistency of these links. Care should be used when
* walking more complex structures that might contain cycles.
