    Fix a latent bug in DAP request decorator
    
    The 'request' decorator is intended to also ensure that the request
    function runs in the DAP thread.  However, the unwrapped function is
    installed in the global request map, so the wrapped version is never
    called.  This patch fixes the bug.
