migration-test has been flaky for a long time, both in CI and

32/648 ERROR:../tests/qtest/migration-helpers.c:205:wait_for_migration_status:
assertion failed: (g_test_timer_elapsed() < MIGRATION_STATUS_WAIT_TIMEOUT) ERROR
on a local macos x86 box:
What is really weird with this failure is that:
- it only happens on non-x86
No, I have seen it on x86 macos, and x86 OpenBSD
- on code that is not arch dependent
- on cancel, what we really do there is close fd's for the multifd
channel threads to get out of the recv, i.e. again, nothing that
should be arch dependent.
I'm pretty sure that it tends to happen when the machine that's
running the test is heavily loaded. You probably have a race condition.
I think I can second that. IIRC I've seen it a couple of times on my x86
laptop when running "make check -j$(nproc) SPEED=slow" here.
And another on-x86 failure case, just now, on the FreeBSD x86 CI job:
https://gitlab.com/qemu-project/qemu/-/jobs/3870165180
And FWIW, I just saw this while doing "make vm-build-netbsd J=4":
