branching: fix wrong merge conflict resolution from
13dfad0f9f7a
13dfad0f9f7a merged stable into default, but accidentally added the
_blockingreader class from stable (but deindented) instead of merging the
changes from stable (
2fe4efaa59af) into the existing _blockingreader class.
This resulted in the _blockingreader being there two times.
