I have a very simple test case in clojure 1.2:

(def * 100000000* (count (range 0 100000000)))

I have a loop running in another thread that periodically causes a full gc and 
then prints the amount of used memory every 2 seconds. Evaluating the above 
form, I get:

Used memory: 0.079951296 G
Used memory: 0.32577516 G
Used memory: 0.847947752 G
Used memory: 1.377162736 G
Used memory: 1.878349032 G
Used memory: 2.202150656 G
Used memory: 2.686696656 G
Used memory: 3.14701836 G

...

Seems like something is holding onto the front of the sequence.

However, if I use the following instead:

(def *100000000* (#(count (range 0 100000000))))

The problem goes away:

Used memory: 0.07999508 G
Used memory: 0.0799572 G
Used memory: 0.07999796 G
Used memory: 0.079997392 G
Used memory: 0.111486904 G
Used memory: 0.079995512 G
Used memory: 0.11590836 G
Used memory: 0.080138968 G
Used memory: 0.080005136 G
Used memory: 0.079963912 G
Used memory: 0.07996396 G
Used memory: 0.079964008 G

Any ideas?
