I try to simulate users using my client application with [Locust][1] for load testing. Users fires some http requests by themselves and besides that the client also has a background thread that fires an http request every x seconds.
How can I simulate the background thread in Locust?
I tried the following and it kind of works but the &quot;background thread&quot; is not stopping when a test is stopped. Apparently that greenlet doesn&#39;t see updates on `self._state`.
```python
class MyUser(HttpUser):
    host = &#39;http://localhost&#39;
    wait_time = between(1,5)
    def on_start(self):
        gevent.spawn(self._on_background)
    def _on_background(self):
        while self._state != LOCUST_STATE_STOPPING:
            gevent.sleep(10)
            self.client.get(&#39;/status&#39;)
    @task(1)
    def main_page(self):
        self.client.get(&#39;/main&#39;)
    @task(2)
    def hello(self):
        self.client.get(&#39;/hello&#39;)
