No "perhaps" about it.  Any network retry loop needs to give up after a few 
tries or have some sort of exponential backoff until the time gets to 
something huge.

In case anybody isn't familiar with it, Dave Plonka did a fantastic job of 
writing up the Univ of Wisc NTP mess:
  Flawed Routers Flood University of Wisconsin Internet Time Server
  http://pages.cs.wisc.edu/~plonka/netgear-sntp/
I think it should be required reading (and understanding) for any computer 
science degree.

Unfortunately, that's not an isolated incident.  Wikipedia has a page on NTP 
server misuse and abuse
