Subject: [PATCH 1/3] We need to generate events when finalizing, or we won't
know that we succeeded in stopping the process to detach/kill. Instead, we
stall and then after our 20 interrupt timeout, we kill the process (even if
we were supposed to detach) and exit.
OTOH, we have to not generate events when the Process is being destructed
because shared_from_this has already been torn down, and using it will
cause crashes.
