This was brought up last year on ros answers and it didn't make it onto the list of todos.

To be specific this is apparently roscpp functionality that never made it in to rospy.

In the answer ken also mentions that a general API cleanup might also be in order.

I think austin implemented this? Check the pull request he has waiting: #6

Correct; I had to reach a bit into the logging module to get the desired behavior, but it's implemented and works for me.

Issues:
- some roswtf tests fail - not sure what the problem is

- Due to use of global variables there are issues with destruction of
global objects in various translation units, during the process
shutdown. This is related to Subscriber and Publisher and happens only
in executables where they are defined as global variables outside of
main. Example: some topic_tools components such as throttle

This is most likely related to the fact that now various components are
statically linked instead of dynamically. And for instance if an
executable depends on rosconsole, and we define a publisher as a global
object, when the program exits, the publisher is getting destroyed, but
other global variables get destroyed before that:
