As we found this subtle "bug"(?) - at least it's questionable why the
'&' was added, which does not change the semantics for the stack var -
by the mails our libVirt build daemon sends to the two of us, I wanted
to raise the question, if this service might be of public interest?

It would be no problem for to forward the mails (max. one per hour,
IFF a new commit could be pulled from the public GIT repository) to
any of the libVirt lists or maybe I'm even able to setup an own one.
I would prefer the first option, though.

Anybody interested?

Ciao
Max
