I don’t know exactly.  I have a feeling that the build farm has been
underused over the last couple of weeks for instance, but no precise
stats.  I’d like to be able to gather usage stats so we can see when the
right time for rebuilds comes.

For now I think we’ll merge core-updates Real Soon, and then start a
staging branch or the python-updates one.
