Move longpoll with changes to current active pool, selecting most suitable source for longpoll, or using any backup pool that has longpoll. Actively stop longpoll if we already have longpoll running and have initiated a longpoll restart. Make the longpoll activation notification warning level to make the switch visible. Change lp_url to alloca to not lose malloced ram.
