Subject: [PATCH] Fix interacting with tools like ruby-debug.

  It seems like the new interactor eats input from $stdin even while it locked.
  This disallow using tools like 'ruby-debug' or 'pry' in specs or cucumber.

  The fix just kills the interactor when it is locked and runs it again when
  ulocked.
