      In this code

      std::stringstream ss;
      ss << "Unable to " << what << " file " << filename << ": " << mongo::errnoWithDescription();
      

      errno is captured too late — it may have been reset by the stringstream by the time errnoWithDescription() uses it.

      There are also a few places where closing the file in response to an error, clobbers the actual errno of interest.
