Clearly, it would require big changes, although compiling to return Promise and using Task.js + yield at call sites would probably be much simpler than CPS conversion.
All call sites, every last Java method => JS function call? That means every single function becomes a generate, all functions use yield and so become generator functions, all calls construct a generator which must have .next() called to get it started. The performance is not going to be tolerable.
This vague suggestion has come up with Emscripten re: sync APIs for workers, and it's a bogus hand-wave. Please don't suggest it as a solution and then make definite plans to reject sync APIs in workers or schedule removal of XHR's async=false mode on a date certain!
