I have a process question as the implementation I have posted on the 
list at
https://www.redhat.com/archives/libvir-list/2012-October/msg00803.html
would need a rebase because of upstream conflicts.
Should I send out new rebased versions once in a while, even if I have 
no other changes or should I wait for initial feedback before producing 
a new patch version?
Thanks.
