That would be great.  It turns out my problem is/was the same as the
folks at MIT.  My linux box is an AFS client.  A person in my
department that is our resident AFS expert informed me that AFS uses
the first 2 group slots to store the AFS PAG (Process Authentication
Group) identifier for the user.  This is for 2.4 and older kernels.  I
don't know if it is the same for 2.6 kernels.  I know the OpenAFS
folks are in the process of redoing PAGs because of 2.6 kernel

For now.  Commenting out the the call to shedPrivileges works for me.
