> - Introduce a lock into WClipboard that protects the code between
>   openClipboard/closeClipboard invocations.
>   The native side does not allow to open the clipboard multiple
>   times or share the opened clipboard between multiple threads.
> 
> - Remove of need to call openClipboard/closeClipboard from
>   getClipboardFormats by using the win32 call
>   GetUpdatedClipboardFormats
> 
> - Prevent a race-condition by not registering the connection
>   between java and native side of clipboard multiple time, but
>   just at construction time.
