Argh. And, which process is reporting an error? nfsd or some of kthreads? In 
the former case, is it possible to create new master-slave process 
tree, rebinding and signalling old tree to exit when all requests are finished?

The same approach is used by www/nginx to both seamless configuration change 
and also binary file upgrade.

CC:ing -current@ to ensure the theme have a bit broader audience.
