These failures are diagnosed by noting the failed pid (in this case 59576), and backtracking to see which test it was attached to (in this case, delete_pools_parallel).

The printing will be flushed only after the process complete, in that case of ceph_test_rados_delete_pools_parallel, we will first create 50 object, since there is no mention in the log for delete_pools_parallel, i think that the first process (create objects) didn't complete (probably failed in some way that we don't know yet).
osds and mons logs do show that the pool created, i need to track if and how many object created for that pool ceph_test_rados_delete_pools_parallel.smithi104-59583

My theory is that fork failed, which caused all the test not to run, this is the only place we won't get any printing.

Running teuthology tests against branch that will add some more message to debug that issue.
