            Bug ID: 37051
           Summary: Provide a way to lock the current global XRay state
           Product: XRay
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Runtime
          Assignee: dberris at google.com

Currently, with the XRay API functions, it's easy to run into a situation where
a currently installed implementation can be unceremoniously uninstalled. We
should provide a stronger protocol for when we're attempting to select a new
mode, and deprecate specific API functions deemed too dangerous to use.

The protocol should include locking the global state, to not allow for
inadvertently interfering with a currently-installed mode.
