[O] :session question

[Andreas Röhler]

Hi all,

org-babel uses the header argument ":session" keeping the environment for 
consecutive evaluations.

That feels the opposite of all on-the-fly evaluations commonly done by a 
(language)-shell.
Commonly a shell keeps is values until a new one is created.

Would find it more natural if ":session" is the default, while a command 
"refresh" makes a new one.

Also instead of ":session" a header argument ":dedicated" would provide a new 
process every time.

As we have a bug around, maybe it's a good moment to consider that,

Andreas
