Sounds cool! =)

Sorry for taking a long time to fully solve these issues. The two/three
reported issues are caused by 2 root causes, however these 2 root causes can
actually affect each other in certain way. Thanks for catching all these
issues.

I will let you run more tests a bit. If everything seems fine, I will push the
patches to upstream.
