Hi all,

I ran into a problem when I ran python scripts where an actionlib
action client is intantiated right after the node a the
wait_for_server() function does not seem to work properly (it just
does not wait).


if __name__ == '__main__':
   rospy.init_node('test_manipulation')
#    rospy.sleep(1.0)

   trajClient =
actionlib.SimpleActionClient("r_arm_controller/joint_trajectory_action",
pr2_controllers_msgs.msg.JointTrajectoryAction)
   if not trajClient.wait_for_server(rospy.Duration(10.0)):
       rospy.logerr("Could not connect to actionserver " )
       exit(1)


will return immediately with an error, even though I would expect it
to wait 10s. If I uncomment rospy.sleep(1.0), everything works always
as expected. Is there a more elegant solution to this?
