So if I get this right, significant speedup for rosmake could be achieved
by replacing yaml.load() with yaml.load(..., Loader=yaml.CLoader) and
yaml.dump with cPickle.dump

Does anyone have the time to investigate whether this also gets us 
significant improvements for any of the other yaml-bound packages that 
we use?
Such as:

rostopic
rosservice
rosbag
rosmsg
rosparam
roslaunch
rospy
actionlib
dynamic_reconfigure
rosdoc

At least for rosbag, I seem to remember seeing complaints about speed on 
answers.ros.org, that could of course be related to something different 
entirely.
