Hey,

Since Thomas brought up changes to dev mode, I've been thinking about
how to implement an incremental dev mode.

After playing with SuperDevMode, it is better (no extensions/etc.), but
AFAICT it still starts over from "let's build a ResourceOracle", "now
let's build a TypeOracle", etc.

Seems like we should be able to reuse ResourceOracle, TypeOracle, etc.,
instances across compiles. And really, have the notion of invoking GWT
dev mode compiles go away altogether. E.g. hook into Eclipse, and
during auto builds have the JS files on disk just magically get updated
after each save.

I've been spiking an Eclipse plugin, which seems not as hard as I
thought it would be, which incrementally generates .jribble files
as .java/.class files change, with the idea of not embedding ecj
anymore. That's a slightly separate topic though.

The only thing that seems impossible with incremental compiles is
preserving the semantics that code generators see--currently they are
very deterministic/batch, and this would change all of that. But for
the better, I think.

(It would invert how GWT currently works--it's a batch system that
sometimes we force (badly) to be incremental, to being an incremental
system which sometimes you could run in batch (on the CLI).)

Does this seem terribly egregious? I think if it worked, it would
result in dramatic productivity improvements--the goal would be
"faster than coffeescript" (or whatever) compiles, and truly instant
refreshes after making changes.
