I am not sure that this is a good idea. The core idea of VNETs
is that they are isolated from each other. If we serialize purging,
then vnets are strongly affecting each other.

AFAIU, from the PR there is some panic fixed. What is the actual bug
and why couldn't it be fixed with having per-vnet thread?
