Launching Programs (example: Vim) from Haskell

Using the Turtle shell scripting library I am trying to launch a program, i.e:

shell "vim" empty

The problem is that this yields the warning Warning: Input is not from a terminal and causes Vim to lag for a few seconds before finally launching.

Questions:

  1. Is shell the best Turtle function to launch an external program from haskell?
  2. If so, is there any way to get around errors like the above?
