  - could the assert be enhanced to print the values of the checked
variables to see what actually failed?

  - I would prefer if in the if-clause, the seemingly more common case
of the buffer should be put first, i.e.

BufferNode* nd = ...;
if (nd != NULL) {
  // work on buffer
} else {
  return false;
}

like it has been in the original code.

Feel free to ignore that last case though.

Also, see Bengt's comments.

Thanks,
  Thomas
