greenlet.join() no longer blocks

using gevent 1.1rc4 os x 10.11 python 2.7.10 (and others)
the greenlet.join method doesn't block, so you can't ever guarantee stuff gets done...

this would be a gevent issue, except it works fine with the same interpreter from the CLI... example code:

#code starts here

from gevent import monkey, Greenlet, hub
import gevent

hub.Hub.resolver_class = ['gevent.resolver_ares.Resolver']
monkey.patch_all()

def sleepy(time):
    gevent.sleep(time)
    print "done like a good script"

if __name__ == '__main__':
    g = gevent.spawn(sleepy,10)
    g.start()
    g.join()
    print "if this is the only log line, then join didn't work"
