/**
* This class implements the global state of a simple reference counting
* collector.
*
* All plans make a clear distinction between <i>global</i> and
* <i>thread-local</i> activities, and divides global and local state
* into separate class hierarchies. Global activities must be
* synchronized, whereas no synchronization is required for
* thread-local activities. There is a single instance of Plan (or the
* appropriate sub-class), and a 1:1 mapping of PlanLocal to "kernel
* threads" (aka CPUs or in Jikes RVM, VM_Processors). Thus instance
* methods of PlanLocal allow fast, unsychronized access to functions such as
* allocation and collection.
*
* The global instance defines and manages static resources
* (such as memory and virtual memory resources). This mapping of threads to
* instances is crucial to understanding the correctness and
* performance properties of MMTk plans.
