Global data is different. Unless global data is placed in a shared data segment (usually via a pragma and DEF file), each process gets its own copy of the global data. So the data is global for a process (for all threads in the process); and not system wide for all processes. Shared data segments are highly discouraged since one process can corrupt the data/state of another process. http://msdn.microsoft.com/en-us/library/h90dkhs0(v=vs.80).aspx.
