You are sending systemctl restart ntpd into the background and kill it 
the hard way. I understand you don't want to wait forever, but killing 
it instantly (while it restarts ntpd) could cause some "funny" 
behaviour. This behaviour might also be somewhat random/racy because the 
kill can happen at different states of the restart.

Can you still reproduce the issue you described if you at least add a 
"sleep 5" before killing systemctl?
