From c604072c6f967e189ac0feab789709e57fbf5ca6 Mon Sep 17 00:00:00 2001

Subject: [svn-r3941] Purpose:     Small Fix Description:     Don't delete the
 /tmp/${USER,LOGIN} directory when we're done with     it. Also, only do the
 /tmp/${USER,LOGIN} if this is a parallel     configured library. Solution:   
  Removed the removal of the /tmp/${USER,LOGIN} directory and added     checks
 to determine if we're in a parallel configured library before     munging the
 filename... Platforms tested:     Linux
