	Within the last year or two, I had a conversation with someone
who claimed to have a machine runn9ing 2.2.x (or maybe it was 2.1.x)
continuously since applying the final security patch.

	From the NetCraft FAQ:

Why do some Operating Systems never show uptimes above 497 days ?

	The method that Netcraft uses to determine the uptime of a
	server is bounded by an upper limit of 497 days for some
	Operating Systems (see above). It is therefore not possible to
	see uptimes for these systems that go beyond this upper
	limit. Although we could in theory attempt to compute the true
	uptime for OS's with this upper limit by monitoring for
	restarts at the expected time, we prefer not to do this as it
	can be inaccurate and error prone.

	... which is not exactly the same thing.
