Yes, looks strange. I tested on quite slow machine, gtk and efl debug builds with RESOLUTION_MEDIA_QUERY disabled and test was executed within few seconds.

If slowness is a problem, we could relax W3C resolution tests and reduce number of queries that are trying to find dpi of the media.

  // Find the resolution using max-resolution
    var resolution = 0;
    do {
      ++resolution;
      if (resolution > 10000) {
        break;
      }
    } while (!query_applies("(max-resolution: " + resolution + "dpi)"));

I think we could change it to "resolution > 500".
Kenneth, what do you think?
