pbuilder != buildd

pbuilder allows you to (rather easily) build a package in a pristine
environment that is newly created from the minimal system. 

AFAIK the buildd are similar, but different as they IIRC use something called
sbuild. Doesn't matter.

What appeals to David and me about the pbuilder is that it helps us to 'nail
down' the Build-Depends. That is important for R with all the R Depends,
LazyLoads etc pp.

Now as you pointed out, there is cost in using pbuilder as the tarball needs
to be built up, brought down, built up, ...  so I think a fair compromise
would be to add a 'bulk' in which we will start from a fresh pbuilder but not
bring it down after each package.

How does that sound?
