/usr/src/UPDATING recommends it because you're going to be
changing executables and libraries out from under currently-running
daemons. This could cause failures in spectacular fashion for any
executables that dynamically load libraries that may have changed
since the time the daemon was started.
If you want to minimize the downtime, do "make buildworld" in
multi-user mode instead, then drop to single-user mode and do "make
installworld" and reboot.
