All I am saying is that there will be no existing product that does
exactly what everyone wants. However, I think it is worth considering JVM
as a starting point close to what we want since it represents a huge body
of solid code.

Clearly, the native support of the standard bytecode is limited, or else
we wouldn't be talking about this project. I think there is a higher level
of abstraction required to do more with it, which would require interaction
with tasking mechanisms to make this useful.

Well, this is discussing one particular idea for "next generation" system.
