Smalltalk images were sort of similar. It's just nice that they went the extra mile to implement it. I'm still waiting for the JVM to have something similar after all these years...

What it did was remarkably close to a core dump. Search for "emacs unexec" to get various pointers as to the complexity and bugs.

How one could reuse this or how it is implemented? Matt: You can't reuse C++ exceptions as they need to capture Javascript level information. So you just return an object that actually represents the exception. The usage of handle_scope is documented here: http://code.google.com/apis/v8/embed.html#handles Marcus: You're mostly correct about the jump. Details are slightly more completed but that's the idea. For preemption I don't know exactly for V8 but my guess is that they generate some loopback to their own code. As for optimizing register allocation, I guess the whole point of compiling straight to assembler is to be able to generate your own optimizations so I would think so yes. anjan: Elaborate on which part of the mechanism?
