rqt process remains when rqt_gui is closed with rqt_bag open on it

[130s]

Closing rqt_gui window doesn't kill rqt_bag's error print. Commandline output is below. I see some errors but not sure how it's correlated.

Observed on 2 different Ubuntu Quantal machines.

Update; this is also a case when rqt_bag is run standalone by $ rosrun rqt_bag rqt_bag.

Looks like the process keeps recording and increases memory usage (with PR2 the amount of memory used can easily get a few GBs within a minute).

Might be linked to the issue #84. Adding "stop recording" function can be a solution.

For now, workaround added to the wiki page.

This turned out to be a failure to call the correct shutdown hooks for rqt_bag. Surprising it didn't blow up closing when it was playing too.
