Yeah, the making of a socket shouldn't at all depend upon the
permissions on a directory where a file is to be saved... it's possible
and happens often that a socket is set up and no data is saved/written
locally.  But then it's possible that the yum code is saying it's a
socket error when it's actually some other kind of error.  We'd have to
examine the source code to ascertain that...  and probably while the
code is running in order to find where in the code the error's being
kicked out.  That's a bit more than I want to get into today.
