I was kind of loose with the terminology -- I don't remember whether it was actually hung in the sense of stopped entirely, or just "sat in a loop waiting for a migration state that never arrives". I'll try to look more closely if I can catch it in the act again. One thing that makes this bug investigation trickier, incidentally, is that the migration-test code seems to depend on userfaultfd. That means you can't run it under 'rr'. -- PMM
