Which namespace binding ?
Isn't 'count eager ?
2010/9/24 Per Vognsen per.vogn...@gmail.com
The namespace binding is what's holding onto the head. This is a
common enough question (which tends to occur more in toy programs than
real ones) that it probably belongs in a FAQ.

Sorry, I posted this question and it turned up under the 1.3 Alpha 1
thread. Apparently you cannot reply to an email from the group, edit
the header, and start a new discussion. Here it is again:
I have a very simple test case in clojure 1.2:
(def *1* (count (range 0 1)))
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 *1* (#(count (range 0 1
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?
