<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I'm a bit concerned about how random the finished argument feels. Maybe we can trigger the deletion of <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">m_proc</code> on the case that it doesn't work and skip the argument altogether?</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I tracked down the root cause of that. In unmount(), m_proc is set to nullptr before the process is killed. And Stderr/StdoutReadReady is triggered after that. So in the signal handler there's a nullptr dereference.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In this patch I take some actions to make sure the process is shutdown properly.</p></pre>
