respawning may mask it.

I stumble across this today:

So there was support to easily start and stop viewman inside FirCAS.
This is evidence that viewman does not need auto respawning --
current behavior is that when ")stopGraphics" stops a viewman process,
sman will start another one.  This should be considered as bug.
