Avoiding copying a moving window of 400 elements 
from a vector of 1,000,000 elements?

That would be the really recent thread -
http://groups-beta.google.com/group/comp.lang.lisp/browse_thread/thread/600943e7decc1b40/f14be5f5e883b0ae?hl=en#f14be5f5e883b0ae

BUT as far as actual, other applications
wouldn't that potentially be good for the sample window
of the _F_ast implementation (power of small integer (2,3) window)
or _F_ourier _T_ransform
