copen_fn (

)
copen_fn(func, args, *keywords) -> file-like object
Open a file-like object that returns the output from function
call. The object's read method returns the return value from
the function. The function is executed as a separate process, so
any variables modified by the function does not affect the ones in
the parent process. The return value of the function must be
pickle-able.
