Sorry, though I got lucky and my overall result is roughly correct,
this is an incorrect time measure. It should be
r <- runif(1); system.time(whatseed(r))
because R's call-by-need semantics don't evaluate the runif before it
starts running whatseed. The correct time (on my machine) is then 28
hours, not 18.
Better to avoid side-effect functions as arguments....
