I've heard it in English as "In the land of the blind, the one-eyed man
is king."

Something pretty much like that has been suggested. My problem with it
is that "n" is a counter that has to be monotonically increasing. That
means that it will eventually hit an archetectural limit. Of course on
my 32-bit machine at 240Hz that limit won't happen until the machine has
been running for about 1/3 of a year, but the limit is there.
