Well, we can later on re-use or define a common API for doing such stuff on
the JVM similar to what perl 5, CPython or CRuby offer by default, and make
sure it is usable.
Regarding the JVM start up time - yes it may be a problem. I was once told
than in JDK-1.5.x the problem was fixed, but I'm not sure if it's true. And if
we see this is a problem in Clojure, we can always opt for writing a new
implementation of Clojure for a different host VM which is better in this
respect. Nevertheless, I think that Clojure would make the best starting-point
for a modern Lisp-based scripting tool.
