Crankshaft is made up of four components:
- a runtime profiler for identifying code that uses a significant number of CPU cycles
- a base compiler for generating code more quickly
- an optimizing compiler which re-compiles code pinpointed by the profiler
- deoptimization mechanism that allows Crankshaft to recover from overly-optimistic code optimizations

It's already happened to the Canary build -- so hit your wrench menu > About Google Chrome and restart to update yourself to Chrome X! There's not much new that you'll notice right off the bat, with the exception of a selectable Instant option and experimental geolocation features in about:flags.
