Something like this is already used in practice, it is called
Profile-Guided Optimization (PGO) and available in GCC (but that uses
AOT, which sounds to me like equivalent to "JIT at startup"). The
OpenJDK-JVM does not support this and I doubt that it will. Maybe GCJ
at some time, but as far as I saw, GCJ does not work with Clojure yet.
