[GE users] Managing user access to scratch space

I would like to set up my cluster such that users do not have the 
permission to directly create directories or files on a compute node 
scratch partition (each of my compute nodes has a large dedicated 
scratch partition).  In other words, I would like to force them to use 
the sge created directory pointed to by TMPDIR so that I know the 
scratch files will be cleaned up when the job is done.

I am guessing that when sge_execd creates the scratch directory it is 
running as user "sge", is that correct?  So if I set up the scratch 
partitions such that the "sge" user has write permission, but not the 
world, this should work?  Right?
