// This tests that module instantiation can succeed when executed a second

// time after a failure.

//

// The first attempt fails becuase module 'a' is not available. The second

// attempt succeeds as 'a' is now available.

//

// This test exercises the path where the previously instantiated module is

// encountered as an import.
