      stdin/stdout handling of the parent process is nicely abstracted away with QProcess.

      On the other hand, getting this right for the child process is quite error prone:

      • reading blocks when stdin is opened using a file descriptor (QTBUG-92905)
      • each read causes 1 F_GETFL and 2 F_SETFL fnctl calls
      • writing is buffered when stdout is opened using a file handle, an explicit flush is necessary (QTBUG-92906)
