The CMS settings are best for low latency applications or applications that
want more predictable pause times. They can cause a drop in throughput for
scientific computing or for Extract-Transform-Load style programs. CMS is
not the default for historical reasons.
The permgen sweeping is
that these settings
are very good defaults for high performance systems.

I believe that local variables are nulled after their last usage to prevent
exactly this behavior. In fact, you can find code like:
Object dummy(Object o, Object dummy) { return o; }
call_stuff(dummy(var, var = null));
In the Clojure source to accomplish this.

You are correct that the sequence of numbers
0.9
0.99
0.999
...
asymptotically approaches 1; however, the number 0.... (with an infinite
number of 9s) is equal to 1. The formal proof of this is fairly tricky as
the definition of the real number is usually done as an equivalence

Boolean.valueOf() was added in 1.4. While that seems ancient, some older
libraries use 'new Boolean()' because they maintain 1.2 compatibility. It
seems like Clojure should take more care when it unboxes Booleans...

There is a project on github that does exactly this.
http://github.com/krukow/clj-ds
I don't know much about the current state of it, but I have plans in the
next month or so to try it out at work.

Doug Lea (of java.util.Concurrent fame) designed a framework called
Fork/Join which is made to separate the idea of work from threads so that
things can be parallelized out as much as possible. I don't know clojure
that well, but would guess that it has some support for it and that you
