> Could this use a relative relocation so that we aren't paying the cost of a dynamic relocation for each global?

@pcc Sorry I missed your comment

I think this is not possible to do for shared objects, because GVs could be preempted. Still this looks possible for executables where I can set
visibility of instrumented globals to hidden. I'll try this out
