 // A base class for compilation jobs intended to run concurrent to the main
 // thread. The job is split into three phases which are called in sequence on
 // different threads and with different limitations:
 //  1) CreateGraph:   Runs on main thread. No major limitations.
 //  2) OptimizeGraph: Runs concurrently. No heap allocation or handle derefs.
 //  3) GenerateCode:  Runs on main thread. No dependency changes.
 //
-// Each of the three phases can either fail, bail-out to full code generator or
-// succeed. Apart from their return value, the status of the phase last run can
-// be checked using {last_status()} as well.
+// Each of the three phases can either fail or succeed. Apart from their return

+//  a) AbortOptimization: Persistent failure, disable future optimization.
+//  b) RetryOptimzation: Transient failure, try again next time.
