Ouch. :-/ Do you envision other needs for extended interpreters? I doubt 
that the Rhino guys will extend that stuff just for us.

I understand actually that ECMAScript has been updated already, so 
eventually they'll have to find a way to integrate those functionalities 
(it doesn't have to be BEA's implementation though).

OK, I see just two ways of dealing with this problem:

1. ask the rhino dev team and see if there is room for them to integrate 
the continuations code: IIRC you had some talk with them and they seemed 
willing to consider it after all (would you be so kind to summarize the 
discussion so far?). If this is the case, ask for the needed changes and 
re-sync the stuff. This is of course the best option;

2. it #1 fails, refactor the rhino core once again, sync the 
continuation code and keep a set of patches together with some GUMP or 
GUMP-like stuff that helps us keeping them in sync with the rhino 

In any case, I don't see as an option forgetting about this issue 
altogether: flow is becoming the next big thing in webapps, which means 
that we'll have to support it in a serious way. Now figure what might 
happen if some serious bug happens in our version, or if the next rhino 
version is 3x faster than ours: we'll have to upgrade in a rush, hoping 
that it's still possible somehow. And yes, I'm a bit scared. :-)
