Hi Edmund,
This is a regression since last Tuesday's commit
f81e612cc9ff91ddefc1d86e270cd7f018701802. Thanks for catching it!

Dear Clojurians,
I have been trying to get a proper grip on the operation of lazy-
seq and hope somebody will have the time to clarify a point for me.
The references indicate that you should not hold onto the head of a
lazy sequence as it blocks the GC. This has lead to me to believe
that a lazy sequence, even while being active 'downstream' can be
GCd 'upstream'. Is this so ?
An example: in this post
http://groups.google.com/group/clojure/browse_thread/thread/57a12f1a0dab5e1b/cb3db6e6ac94092f?#cb3db6e6ac94092f
in the first version of fibo, the call (nth (fibo) 1000000) will
cause a seq to proceed to the millionth element. If memory were
tight could earlier elements be GC'd before nth had reached the
end ? My understand is that it can. I ask because on my machine on
Clojure 1.2, (nth (fibo) 1000000) causes a heap overflow which I
don't understand.
Thanks in advance,
Edmund
