--EXPECT--
FunctionObject dies now!
Should output Hello World string
get nonexistent 1
Should output Hello World string
get nonexistent 2
Should output Hello World string
get nonexistent 3
Persistent should be removed
Should output Hello World string
get nonexistent 3
Should output Hello World string
get nonexistent 3
Context dies now!
Context should be removed
We are done for now
Isolate dies now!
