    emulation: Limit integer arguments to 65535
    
    To guard against malicious sequences containing excessively big numbers,
    limit all parsed numbers to 16 bit range. Doing this here in the parsing
    routine is a catch-all guard; this doesn't preclude enforcing
    more stringent limits in the handlers themselves.
