[Fab-user] Wait for parallel task to complete

[anatoly techtonik]

Hi,

Is it possible in fabric to wait until a subtask completes on all
servers successfully before moving to next step?

For example, in the snippet below I want update() to execute only
after test() passed on all servers.

def test():
   _some_tests()

def deploy():
  test()
  update()
