are you sure this isn't just size?  printf doesn't write the trailing '\0',
that's just a signal to stop printing.

In Release, should fBytesWritten always == 0?  That's what this seems to do.

[mtklein, 2014/03/06 18:28:11]

Oh, good catch.  This should be += size.

It seems fine that bytesWritten() always returns 0 in release.  It's consistent
with the bytes actually written.

     return true;
