Before approving this, I want to understand the impact on the build 
logistics with 6940241.  In particular, what happens if:

* A fresh hg fclone is done and a "make" command is issued from the root 
directory?
* If allow.downloads is made true, do subsequent builds always download 
or do they first check for a matching file in the build directory?
