The problem is that logLevelString() implementation in WebKit layer doesn't take RELEASE_LOG_DISABLED into account. Actually the implementation of logLevelString() in all layers does the same, getting th value of WEBKIT_DEBUG env var, but with a few differences. We can have a single implementation in WTF and use WTF::logLevelString() from WebCore and WebKit.
