or something else that needs cleanup). I can't wrap the consumer in a

Is there a general method for cleaning up after the consumer discards
its reference to that lazy seq? I'm vaguely aware of Java finalize,

For the binary distribution, it's not hard. I could setup a CI project
at http://teamcity.codebetter.com and put together some binaries to
download.
Regarding Stability and speed, it's way too early for me to comment
since I'm a newbie with Clojure so I couldn't really comment.

Hi,
I've read the src of core.clj of Clojure 1.1.0. Originally I thought
the meaning of #_ is to comment the thing after it, sort of like `;'.
But the in the src of core.clj in 1.2.0-RC1. The definition of reduce
is overrided to use the internal-reduce function. The defn line, is
preceded by `#_'.
