title: Is there a fast language that supports portable continuations?
body: <p>I'm looking for a fast language (ie. a language that can be compiled natively to achieve performance not more than 3 or 4 times slower than C), which supports portable continuations.  By this I mean a continuation that can be serialized on one computer, and deserialized on another.</p>
  
  <p>I know that SISC can do this (a Scheme implementation in Java), but its slow.  Ditto for Rhino (a Javascript implementation in Java).</p>
