Review Comment:
Yes, this should happen if the `taskMemoryManager.allocatePage` method
returns. But in our production environment, `allocatePage` keeps throwing
OutOfMemoryError (OOM), causing recursive calls to `allocatePage`, eventually
leading to the Executor exiting abnormally without entering the `throwOOM`
method.
