Question regarding JIT

[Millsa Erlas]

I heard that Parrot has a JIT compiler. If I understand this correctly, 
does this mean Parrot bytecode is converted to native machine hardware 
code before execution? If so, it is a good idea.

JIT is great, however, will it still be possible to run the Parrot 
bytecode on the interpretor?

Also, does the native machine code make calls to the Parrot VM, for 
thinks like storing variables, calling subroutines, and so on? This 
makes sense, since Parrot can still manage memory allocation, and other 
things for the machine code.
