For the error message, I suggest including both os.getuid and prop.st_uid,
e.g. something like:

".netrc file is owned by (%d); should be (%d)" % (prop.st_uid, os.getuid())

NetrcParseError seems a little odd but I suppose I could justify incorrect
ownership or mode as a parse error.  We definitely don't want to introduce a
new exception for 2.6.9, so the only other option is an OSError I think.

RDM, can you write any tests for this issue?  Also, are any documentation
changes necessary?  I think this should be a candidate for 2.6.9.
