    [SHELL32_APITEST] ShellExecCmdLine: Do **NOT** use TerminateProcess to close the
opened windows.
    
    This design, introduced in 418edcd2b, is fundamentally flawed as it
    can also close windows unrelated to the running test (e.g. windows
    of programs that the user can start, while the test is running).
    
    But since we cannot do much better, mitigate instead the other main
    problem of this design: Just use PostMessageW(WM_CLOSE), as it used
    to be, instead of TerminateProcess().
    
    Indeed, using TerminateProcess() otherwise could kill unrelated
    processes the test hasn't created. In particular it could kill the
    csrss.exe system process if, during the testing procedure, a hard-error
    popup shows up.
    And this is precisely the case when this test runs with limited memory,
    and a hard-error
      "Insufficient system resources exist to complete the requested service."
    arises.
