you can see the client (bottom) send the requests to the server(top), do some other work, and then start
to check/wait on the tasks. Kind of like calling thread.join(). The job with id ending in 187 finished
much quicker than the other one. You can tell because the client only had to send one POST request for 187
after doing its own work, meaning it was already done. From there it just had to wait on 191.
