Number of users reduce after running for 1min

[GuoTengda1993]

Description of issue

I start a new locust test, set user number 10, swarm 5; after 1min, the user number reduce to 0, but RPS is stable.

Expected behavior

stable test

Actual behavior

Environment settings

• OS: Windows
• Python version: 3.7
• Locust version: 0.11.1

Steps to reproduce (for bug reports)

Any websit to test, set user 10, swarm 5

class PressureTest(TaskSet):

    def setup(self):
        global headers
        headers = [{"Content-Type": "application/json"}]

    @task(100)
    def test1(self):
        query = {}
        with self.client.get('https://www.baidu.com', headers=headers, params=query, verify=False, catch_response=True) as resp:
            if resp.status_code == 200:
                if b'b' not in resp.content:
                    resp.failure('Error: wrong response --  ' + resp.content.decode('utf-8'))
                else:
                    resp.success()
            else:
                resp.failure('Error: wrong status code -- ' + str(resp.status_code))



class ApiTest(HttpLocust):
    host = ''
    task_set = PressureTest
    min_wait = 300
    max_wait = 500
    stop_timeout = 60

• please provide example code

Misunderstanding "stop_timeout", it's not the time to assert failure when response time exceed it.
