We've talked about trying to implement this strategy (load everything, dump/restore the heap) with MRI, but our thought experiment was on the scale of a fully-booted application. In that context, it gets difficult to determine how to proceed when an application source file has changed, since re-loading isn't safe in ruby. It's a really interesting idea to pre-load the heap with just a set of libraries, which wouldn't be subject to as much change.
