Hi Bjoern,

Trying to move the discussion over to Phabricator at:

The answer to your question I believe is this commit:

It affects both IPv4 and IPv6.

I know that sometimes multicast entries can be freed from timer 
callbacks. I think having a task, probably one is enough, for network 
related configuration is acceptable. With D24914 there will be two 
threads to teardown which is probably overkill, but anyway makes a solid 
solution for now.

I don't know why Stephen didn't think about draining those tasks. I know 
some people are not actively using VIMAGE and that might be the reason.
