Subject: [PATCH 4/4] iotests: Make 144 deterministic again

RH-Author: Stefan Hajnoczi <stefanha@redhat.com>
RH-MergeRequest: 352: monitor: only run coroutine commands in qemu_aio_context
RH-Jira: RHEL-7353
RH-Acked-by: Kevin Wolf <kwolf@redhat.com>
RH-Acked-by: Hanna Czenczek <hreitz@redhat.com>
RH-Commit: [4/4] 4974a32174abefb509b7c46671a364b4b991449e

Since commit effd60c8 changed how QMP commands are processed, the order
of the block-commit return value and job events in iotests 144 wasn't
fixed and more and caused the test to fail intermittently.

Change the test to cache events first and then print them in a
predefined order.

Waiting three times for JOB_STATUS_CHANGE is a bit uglier than just
waiting for the JOB_STATUS_CHANGE that has "status": "ready", but the
tooling we have doesn't seem to allow the latter easily.
