  Log Message:
  -----------
  iostream-temp: If write() to temp file fails at any time, move it back to memory.

Similarly to if the write() to temp fails during the initial move attempt.
This way even if write() fails due to out of disk space, it's not visible
to caller. An error message is logged in any case.
