Yes, for "advertised" globals we'd have to make aliases and arrange for them to be shared. But, the idea is to avoid odd problems like the one I hit, where test ordering can cause errors due to minor clashes from the choice of local-to-the-.exp variable names. In the end it is probably simpler to just fix our tests when random issues crop up, than it is to try to fix dejagnu. Plus maybe we could use namespaces more in our own tests or something like that.
