<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This should be 1 instead of 0 given the changes you've made elsewhere (unless the existing value is a bug...).
But, the entire set of changes to reference count handling appear to be unnecessary. Why the change?</pre>

Since this maybe nullEngine is wrong to be 1 or -1. One engine that is not refered must be invalid and useless. Manager must decide.</p></pre>
