Why so complicated?

A simple strace shows that the native Windows call CreateProcess() fails
with error 87.

$ net helpmsg 87
The parameter is incorrect.

Another simple look into MSDN for the CreateProcess call reveals:

  lpCommandLine 
    [in, out] Pointer to a null-terminated string that specifies the
    command line to execute. The maximum length of this string is 32K
    characters.
