When issuing "ipsec stop", starter tries to shut down the IKE daemon. If
that does not happen fast enough, starter gets more aggressive in
killing the process to bring it down. Details can be found at [1], you
may change that for your needs.

Also, please be aware that UDP is unreliable, and even if charon sends
all messages, they might get lost on your network or even in your local
networking stack.
