And finally I'm here :)

Thanks a lot for doing this job and for your explanations in other threads which
I'm reading today and sorry for the delay! I'll look through these series soon.

Actually, my second child (girl:) was born a month ago, and then her elder brother
was ill, so I took two weeks sick leave after about two weeks vacation and forget
about work for a month.

Hmm. And Nikolay, who doing libvirt part is on vocation now (I started bitmap remove
transaction series by his request), so I don't know about the end of the story with
release and this functionality..

Anyway, it's cool, thanks!
