I've no idea. Perhaps you never send SIGTERM to the vmlinux process, or maybe this is just a very strange bug. Although it happens reliably in two tests from the test suite, it doesn't happen in any of the other tests (about 100 of them). Perhaps I'm wrong about the nature of the bug and the signal is coming from somewhere else. Is there a way that a process inside the guest could send a signal to a process on the host? (I would hope not, but have to ask in case something in the guest is going rogue).
