I had thought of that too, but I think the way `classTrack_reset()` is called,
it is likely not possible for there to be a `classTrack_processUnloads()` also
coming in because everything is shut down:
```
threadControl_onDisconnect();
standardHandlers_onDisconnect();
/*
* Cut off the transport immediately. This has the effect of
* cutting off any events that the eventHelper thread might
* be trying to send.
*/
transport_close();
debugMonitorDestroy(cmdQueueLock);
/* Reset for a new connection to this VM if it's still alive */
if ( ! gdata->vmDead ) {
debugInit_reset(getEnv()); <--- calls classTrack_reset()
}
