-// Some collectors will perform "process_strong_roots" in parallel.
-// Such a call will involve claiming some fine-grained tasks, such as
-// scanning of threads and code blobs.
-// Claiming of these tasks requires that sequential code calls
-// initialization methods to set the claiming code in the right
-// state for parallel task claiming.
-// StrongRootsScope is a way to capture such setup code to make
-// sure that it is executed in the correct way.
+// Sets up and tears down the required state for parallel root processing.
