// Flags: --harmony-async-await
// The test observes the callbacks that async/await makes to the inspector
// to make accurate stack traces. The pattern is based on saving a stack once
// with enqueueRecurring and restoring it multiple times.
// Additionally, the limited number of events is an indirect indication that
// we are not doing extra Promise processing that could be associated with memory
// leaks (v8:5380). In particular, no stacks are saved and restored for extra
// Promise handling on throwaway Promises.
// TODO(littledan): Write a test that demonstrates that the memory leak in
// the exception case is fixed.
