join (and joinall) will pause the current greenlet till the ones you've
joined terminate (similar to the threading.Thread join method).
gevent.sleep will suspend the execution of the current greenlet and let
other greenlets get some time to execute.

Neither of these are *necessary*. Just creating a greenlet and
`.start`ing it will make it run similar to a thread as long as other
greenlets don't hog the CPU and have some calls that can context switch.
