  23  * Implementation details on Win32.
  24  *
  25  * - There is no way to set the no-inherit flag for
  26  *   a "file descriptor" in the MS C runtime. The flag is there,
  27  *   and the dospawn() function uses it, but unfortunately
  28  *   this flag can only be set when opening the file.
  29  * - As there is no fork(), we cannot reliably change directory
  30  *   before starting the child process. (There might be several threads
  31  *   running, and the current directory is common for all threads.)
  32  *
  33  * Thus, we must in many cases use a helper program to handle closing
  34  * of (inherited) file descriptors and changing of directory. The
  35  * helper process is also needed if the standard input, standard
  36  * output, or standard error of the process to be run are supposed to
  37  * be redirected somewhere.
  38  *
  39  * The structure of the source code in this file is a mess, I know.
