-    // Note that you can use this handle to schedule any number of exits. This capability is here for
-    // two reasons:
-    // 
-    // - B3 code duplication. B3 could take a patchpoint and turn it into multiple patchpoints if it
-    //   duplicates code. Duplicating code is legal since you can do it without changing the behavior
-    //   of the program. One example is tail duplication. Another is jump threading. Yet another is
-    //   path specialization. You will have one PatchpointExceptionHandle per patchpoint you create
-    //   during DFG->B3 lowering, and that patchpoint will have a generator that calls
-    //   handle->scheduleBlah(). That generator will be called multiple times if your patchpoint got
-    //   duplicated.
-    //
-    // - Combination of unwind and non-unwind exception handlers inside one patchpoint. A GetById may
-    //   need both an exception handler that serves as an unwind target and an exception handler that
-    //   is branched to directly for operation calls emitted inside the patchpoint. In that case,
-    //   you'll call both scheduleExitCreation() and scheduleExitCreationForUnwind() on the same
-    //   handle.
-
-    // Schedules the creation of an OSR exit jump destination. You don't know when this will be
-    // created, but it will happen before linking. You can link jumps to it during link time. That's
-    // why this returns an ExceptionTarget. That will contain the jump destination (target->label())
-    // at link time.
