(Byte Code) VM loops over a set of bytes and executes them according to the set

invokes the JIT VM in a seperate goroutine and compiles the byte code in JIT

The JIT VM, when invoked, loops around a set of pre-defined instructions until
it either runs of gas, causes an internel error, returns or stops. At a later
it either runs of gas, causes an internal error, returns or stops. At a later
stage the JIT VM will see some additional features that will cause sets of
instructions to be compiled down to segments. Segments are sets of instructions
