The problem is: what is a reasonable value?

Shutting down Windows can take literally hours if there are pending 
updates; that's of course unacceptable if you are running other services 
and need them up again in a reasonable time.

Solution, of course, is not shutting down VMs, but suspending them.
IIRC that is coming in bhyve in the future.
