  o Code simplifications and refactoring
    - Use unbuffered I/O for utility functions around the process_handle_t
      type. This fixes unit test failures reported on OpenBSD and FreeBSD.
      Fixes bug 21654.
Remove buffered I/O stream usage in process_handle_t. This patch removes the buffered I/O stream usage in process_handle_t and its related utility functions. This simplifies the code and avoids racy code where we used buffered I/O on non-blocking file descriptors.
