Should be fine, just backported it to branch. Though actually that 
shouldn't be needed at all, the documentation for updateScreen says:

     * This method could be called very often by engines. Backends are hence
     * supposed to only perform any redrawing if it is necessary, and 
     * return immediately. For a discussion of the subject, see

Thus as I get it it should be fine to call updateScreen as often as I 
want without it taking up any real processing time, apart from jump, 
branch, return.
