> Use SIGTERM in replace of SIGQUIT
>
> SIGTERM is the normal signal to use when instructing a process to exit.
> The only difference is that an unhandled SIGQUIT is meant to generate a
> coredump, which is not what we want, but in practice I encountered an
> issue where SIGTERM seemed to be deliverable more reliably than SIGQUIT
> (in tests using multiple signal helpers).
