Worth pointing out that in a cloud-universe where instances are killed and restarted, improving startup time is actually money on the table, since work performed by guice at startup costs CPU time which most cloud vendors charge for. Perhaps a trickle, but still a "good thing" to fix where Guice (or any software) is doing unnecessary work.
