Of course, if you reboot 64 nodes at once and they all try to download
from the front end node at the same time, then five seconds to download
one node turns into five minutes to start up the entire cluster.

However, I agree that this isn't really significant.  People who really
care can put gigabit on the master node and cut that down to 30 seconds.
