rosmaster doesn't fully clean up closed sockets (Groovy)

[tfoote]

When nodelets shutdown the rosmaster doesn't cleanup all it's sockets correctly.

You can simply verify that problem by launching nodelet_tutorial_math.

$ lsof -nl | grep rosmaster | grep -c CLOSE_WAIT
=> 0
$ roslaunch nodelet_tutorial_math plus.launch
Ctrl-C
$ lsof -nl | grep rosmaster | grep -c CLOSE_WAIT
=> 4

Repeated running and stopping of a nodelet causes the count of CLOSE_WAIT sockets to increase.

Originally filed ros/nodelet_core#10
Marking as minor and untargeted.

@garaemon FYI

This affects Groovy only. In Hydro the problem has already been fixed.

Since the necessary changes are not likely to be backported you might want to consider upgrading to Hydro.

I think this problem still exists on the latest hydro
