Do they still leak memory?  From http://c2.com/cgi/wiki?EmacsLisp :

"Note that variables bound with lexical-let are never released, even
if they are never used. Try

 (loop for i from 1 to 100000 collect (lexical-let ((x i)) '()))

and watch it eat memory. So making infinity (ZeroOneInfinity) lexical
variables is out of the question except for very small values of
infinity."
