> Tests that use the {{StartSlave}} test helper are generally fragile when the test fails an assert/expect in the middle of the test. This is because the {{StartSlave}} helper takes raw pointer arguments, which may be stack-allocated.
> In case of an assert failure, the test immediately exits (destroying stack allocated objects) and proceeds onto test cleanup. The test cleanup may dereference some of these destroyed objects, leading to a test crash like:

> The {{StartSlave}} helper should take {{shared_ptr}} arguments instead.
> This also means that we can remove the {{Shutdown}} helper from most of these tests.
