Yes, I agree that the docs are a little confusing. The returned handle
cannot be used directly by SysOpenEventSem, but the event semaphore you
created can now by opened using SysOpenEventSem. Generally, you would have
a master process, such as a server, that creates the semaphore. That
process would not use open, but directly use the handle returned by create.
Other processes that need to use this semaphore would call open to get a
local handle and will use that handle to post events, etc.
