killing suspended jobs makes zsh hang after 47d1215

[Pan Tsu <inyaoo@xxxxxxxxx>]

With 4.3.12 I can't cycle between open docs a la bookmarks.

  % env -i TERM=xterm =zsh -f
  % man man
  ^Z
  zsh: suspended  man man
  % kill %
  % %
  [1]  + continued  man man
  load: 0.04  cmd: zsh 47317 [pause] 222.05r 0.01u 0.00s 0% 2612k

In case it's harder to reproduce here is a trace
