If this indeed is reproducible, I think it should be fixed.

I would say so, just with the problem that I can't reliable say what 
"accordingly" here would be (and hence I can't craft a patch I can guarantee 
will work at least in most of the cases).

And as said before, I'm also not convinced that using the maximum possible 
number of vCPU-s for this initial calculation is really the right thing to do.
