The is_gemini logic is too simple: as just observed on a SeaStar system, it can
be fooled into the wrong result if more than 1 row has NULL coordinates. 

This case happens if a blade has been powered down completely, so that the SeaStar
network chip is also powered off. The routing system recognizes this case and 
routes around the powered-down node in the torus. It is plausible that in such a
case the torus coordinates are NULL, since the node(s) are no longer part of the
torus. 

(It is also possible to set all nodes on a blade down, but leave power switched
 on. The SeaStar chip, which is independent of the motherboard, will continue to
 provide routing connectivity, i.e. the torus coordinates would all be non-NULL,
 but no computing can be done by the node, the ALPS state is "ROUTING".)

Here is the example which revealed this behaviour: one blade, nodes 804-807,
had been powered down after system failure.

mysql> select COUNT(*), COUNT(DISTINCT x_coord,y_coord,z_coord) FROM processor;
+----------+-----------------------------------------+
| COUNT(*) | COUNT(DISTINCT x_coord,y_coord,z_coord) |
+----------+-----------------------------------------+
|     1882 |                                    1878 | 
+----------+-----------------------------------------+

==> There are 4 more node IDs than there are distinct coordinates.

mysql> select processor_id,x_coord,y_coord,z_coord from processor\
       WHERE x_coord IS NULL OR y_coord IS NULL OR z_coord IS NULL;
+--------------+---------+---------+---------+
| processor_id | x_coord | y_coord | z_coord |
+--------------+---------+---------+---------+
|          804 |    NULL |    NULL |    NULL | 
|          805 |    NULL |    NULL |    NULL | 
|          806 |    NULL |    NULL |    NULL | 
|          807 |    NULL |    NULL |    NULL | 
+--------------+---------+---------+---------+

==> The corrected query now also gives the correct result (equality):
mysql> select COUNT(*), COUNT(DISTINCT x_coord,y_coord,z_coord) FROM processor\
       WHERE x_coord IS NOT NULL AND y_coord IS NOT NULL AND z_coord IS NOT NULL;
+----------+-----------------------------------------+
| COUNT(*) | COUNT(DISTINCT x_coord,y_coord,z_coord) |
+----------+-----------------------------------------+
|     1878 |                                    1878 | 
+----------+-----------------------------------------+

BLUEGENE - Fix for handling extremely overloaded system on Dynamic system dealing with starting jobs on overlapping blocks.  Previous fallout was job would be requeued.  (happens very rarely)

not recognize. The options may be from a newer version of sview.

This sets cursor visibility to 0 in smap mode, it is restored after the
call to endwin().

This restores the if condition so that do_basil_confirm() is
also executed in the stepdmgr (otherwise batch jobs would fail).
