The old provider is stuck on the way back from the device to my console

It's important for me to still use the old provider because of bugs with the new provider, using pulses. I'll try to create small examples and open separate issues.

When I run a simple circuit on the old provider:

from qiskit import QuantumCircuit, IBMQ

IBMQ.load_account()

provider = IBMQ.get_provider(<details>)
backend = provider.backend.<backend name>

circ = QuantumCircuit(1, 1)
circ.x(0)
circ.measure(0, 0)

res = backend.run(circ).result()
print(res.get_counts(0))

I can see on the IQX page that the job completed successfully. But my console gets stuck and never reaches the print line.

With the new provider it works fine.
