This seems to have been it.  Changing "$SGE_ROOT" to "$SGE_ROOT/bin"
let SGE came up ok in a couple of consecutive reboots.  Not definitive
proof that was the issue, but at least it seems like progress. 
Apparently it was getting to this part of the SGE init script before
$SGE_ROOT was actually mounted, the -d test always passed, NFS
mounted or not, and of course the SGE start up failed since none of that
code from the remote system was reachable.  Just for kicks I added an
echo line within the loop, so that if it sticks there it will show
up on the console.
