Good point. How about something like this?

"The Windows port so far used process handles as PID. However, this is not consistent with what getpid returns.

PIDs are system-global identifiers, but process handles are local to a process. Using PIDs instead of process handles allows for instance a user to kill a hung process with the Task Manager, something that would have been impossible with process handles."
