[issue12540] "Restart Shell" command leaves pythonw.exe processes running

Here's a simple reproducer for the same problem, without the context of IDLE. As far as I understand, what IDLE's spawn and then kill process are doing is:

  import os
  from signal import SIGTERM

  pid = os.spawnv(os.P_NOWAIT, "notepad.exe", ['notepad.exe'])
  print('pid = %s, SIGTERM = %s' % (pid, SIGTERM))
  os.kill(pid, SIGTERM)

Running this, the notepad.exe subprocess stays alive after the script exits, and I get the error:

  pid = 1868, SIGTERM = 15
  Traceback (most recent call last):
    File "k.py", line 6, in <module>
      os.kill(pid, SIGTERM)
  WindowsError: [Error 87] The parameter is incorrect
