-Tests the behavior of Array.prototype.concat while the array is having a bad time due to one of the elements we are concatenating.
+This tests that speculation recovery of destructive additions on unboxed integers works.
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
