Code review comment for lp:~alecu/ubuntuone-control-panel/webclient-shutdowns

The branch looks good, but I'm getting this in windows:

===============================================================================
[ERROR]

As far as I can see, if the test finished because d2 was fired, the deferred d3 leaves the reactor unclean with the callLater thing added.
