The problem is that it's also not uncommon for the fileserver to
completely or nearly completely stall when shutting down, so unless bos
kills it your fileserver is going to be down for hours and hours. That's
the reason for the eventual kill. At some point, it becomes faster to
salvage than to wait for the fileserver.
I could certainly see making the timeout an option, though, so you can
choose not to ever kill your fileserver if you want to manage that
