This was the problem with Mira that we went through with Jeff H. last week.  Where getting the home directory was failing occasionally and hanging the system.  So I was told to use -skip_petscrc on the command line, which failed to get the code to skip the (user) RC file.  In looking at the code I realized that you need to not give PetscInitialize() an RC file name.   So we need to change the code slightly but it took a while to figure that out (e.g., I had to look at the source).
