After decoupling the startup of senders and receivers during fragment execution, cancellation of queries can lead to 'zombie' fragments waiting for the other end to get started. Those fragments will time-out after 2 minutes, however due to queuing effects it can take several minutes until all of them are gone. It is therefore currently not feasible to wait for the 'impala-server.backends.client-cache.clients-in-use' metric in the tests.
