migration-test is still intermittently hanging on this machine.
Can we either:
 * add enough tracing and debug to this test that we can get
   logging from it to tell us what is failing
 * disable the test

This is hampering the automated CI because gradually the CI
runner slots fill up with stuck jobs. (I don't know why the CI
runner is not killing the processes when the job itself times out.)
