| 183 <p> | |
| 184 Module function used to allow for debugging of multiple threads. | |
| 185 </p><p> | |
| 186 The way it works is that below, we reset thread._start_new_thread to | |
| 187 this function object. Thus, providing a hook for us to see when | |
| 188 threads are started. From here we forward the request onto the | |
| 189 DebugClient which will create a DebugThread object to allow tracing | |
| 190 of the thread then start up the thread. These actions are always | |
| 191 performed in order to allow dropping into debug mode. | |
| 192 </p><p> | |
