"""Regression tests: cron dashboard handlers must not run profile I/O on the event loop.

Guards the residual sites missed by the 49fa04a23/346e5673d threadpool
migration: POST /api/cron/fire (_find_cron_job_profile) and
POST /api/cron/blueprints/instantiate (_call_cron_for_profile create_job).
Each stub asserts it is running OFF the event loop thread by checking that
no running asyncio loop is present in its thread.
