-// 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: |
