-// C++ calls into script contexts which are "owned" by WebKit (created in a
-// process where WebKit.cpp initializes v8) must declare their type:
-//
-//   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 this class.
-//
-// 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 V8RecursionScope in the same
-// block as the call into script. Calls of type (3) should stack allocate a
-// V8RecursionScope::MicrotaskSuppression -- this skips work that is spec'd to
-// happen at the end of the outer-most script stack frame of calls into page script:
-//
