I did install haveged which indeed seems to help quite a bit. But now after having used an xlarge (8 CPU) instance for a while, I again get hanging processes, like
ubuntu 2317 0.0 0.0 0 0 pts/0 D+ 16:14 0:00 [tail] I used that tail on /var/log/lxd/lxd.log to see what's going on. lxd itself stopped responding much earlier (but not in kernel "D" state, it's sleeping).
