    Windows: cope if caret blinking is disabled.
    
    On Windows, when a blinking cursor is enabled, PuTTY uses the system
    default blink time from GetCaretBlinkTime(), which can be configured in
    Control Panel.
    
    Control Panel allows caret blinking to be disabled entirely, in which
    case GetCaretBlinkTime() returns INFINITE. PuTTY wasn't handling this
    case; if cursor blinking was enabled in PuTTY but disabled at the system
    level, the terminal window would hang, blinking the cursor madly.
