    param: New h2_window_timeout parameter
    
    This parameter needs to be somewhat high because web browsers may for
    example only credit streams for image resources just enough to parse
    metadata like width and height of a picture in order to perform layout
    computations and fetch resources more sensitive to latency before the
    effective image payloads.
