| <FONT color="green">066</FONT> * is a possible alternative solution: rewrite release() so it merely<a name="line.66"></a> |
| <FONT color="green">067</FONT> * posts a request for release onto a threadsafe queue, and explicitly<a name="line.67"></a> |
| <FONT color="green">068</FONT> * process that queue on an infrequent basis during main-thread<a name="line.68"></a> |
