I was wondering what if you call exec and the result of the call, which has
stdout, stdin, stderr.. you pipe to the current process stdout, stdin and
stderr:
var vi = exec("vi...
vi.stdout.pipe(process.stdout)
process.stdin.pipe(process.stdin)
vi.stderr.pipe(process.stderr)
Does this works? Why not?
