 @brief    Given a Mac OS X system error code, tries to return
 an error with one of the Mac OS X system domains and
 localized description.
 
 @details  If you give it a known combination of domain and code, 
 and nil userInfo, -[NSError errorWithDomain:code:userInfo:] will 
 sometimes fill in the localized description, at least for errors
 in NSOSStatusErrorDomain and NSMachErrorDomain.&nbsp;  This method
 tries to use that capability, but I need more documentation to 
 make it work better.
