why not call ServiceListener.remove_service?

[ukaiyuan]

a.py
zeroconf.add_service_listener

b.py
zeroconf.register_service

c.py
import psutil
process.kill("python b.py pid")

why not call ServiceListener.remove_service?

[ukaiyuan]

b.py
zeroconf.unregister_all_services()
zeroconf.close()

this is ok
