I intended to remove this line in 29ef7ecf - see my notes there for details.

The assertion here is causing many spurious failures that aren't
actually relevant to the test itself.

We are tracking the cause for this failure independently, and it would
make more sense to have a dedicated test for clean shutdown.

Noticed few places where tests seem to block indefinitely and panic
after the test run reaches the test package timeout.

I intend to follow up with the proper fix later, but timing out is much
better than indefinitely blocking.

Sadly can't move the fingerprint timeout tweak into the helper due to
circular imports.
