To repeat others and the documentation:

  In either case, the arguments to the child process should start
  with the name of the command being run, but this is not
  enforced.

The argument list must contain the executable as its first
argument. Python indeed crashes if I don't include the first
argument as directed.

In any case, on Windows I would normally need to do something
like this instead:

os.execlp('cmd.exe', 'cmd.exe', '/K', 'ping.exe')
