-// C++ calls into script contexts which are "owned" by blink (created in a

-//   1. Calls into page/author script from a frame
-//   2. Calls into page/author script from a worker
-//   3. Calls into internal script (typically setup/teardown work)
-//
-// Debug-time checking of this is enforced via v8::MicrotasksScope.
-//
-// Calls of type (1) should generally go through ScriptController, as inspector
-// instrumentation is needed. ScriptController allocates V8RecursionScope for
-// you.
-//
-// Calls of type (2) should always stack-allocate a
-// v8::MicrotasksScope(kRunMicrtoasks) in the same block as the call into
-// script.
-//
-// Calls of type (3) should stack allocate a
-// v8::MicrotasksScope(kDoNotRunMicrotasks) -- this skips work that is spec'd to
-// happen at the end of the outer-most script stack frame of calls into page
-// script:
