main task is idling, original design using the main task to listen to the sfp change event, can we reduce one thread here? have you compared the time consuming of xvrd before and after, any significant increase?

@keboliu before changes on stop ~10 sec, after changes ~1 sec.
The idea is to use main daemon process to:
- Do init
- Handle signals
- Manage tasks
- Do deinit
This is a different architecture approach.

xcvrd shutdown flow is broken due to a platform_sfputil.get_transceiver_change_event() blocking call which uses epoll_wait. This function affects process signal mask and signal handlers are not getting called.
