---------------------------------------------

Hi Daryn,
Looks this patch deletes the file if it fails to write completely.
I remember the old behavior was that the partial file still presents. I don't see any discussion about this behavior change here. Is this discussed somewhere?

{code}
      tempFile = null;
    } finally {
      if (tempFile != null) {
        tempFile.fs.delete(tempFile.path, false);
      }
    }
{code}
