SE_SELFSE_SHARED_SERVICES
This object is used in the ScriptEase builds that allow objects to be shared among contexts. In builds in which this is not turned on, it is a synonym for SE_SERVICES. This means you can use this object to make your code work correctly when shared and still compile and function in a non-shared build.
See the SHARED SERVICES section in the Fibers and Threads chapter for a complete discussion of sharing objects and using this stock object.
