I think most of the runtime language developers, myself included will kill to 
have this feature included into the JDK.
There are several features of dynamic languages that are currently hard to 
implement like type specialization, stack reification, as you said fibers, and 
more generally de-optimization that will be far easier to implement with that 
capability (currently only Nashorn can afford to implement some of these
