If I recall correctly I dropped the MPI summary line when merging 1.8 
core, as I made the MPI code as similar to --fork code path as at all 
possible. I might look into re-implementing that summary if you really 
need it.

In your example you are running batch mode. Node 3 and others are still 
in stage 2/3 and their ETA show when /that stage/ will finish. Nodes 1, 
2 and 8 has already entered stage 3 and show no ETA because it's beyond 
year 2029 or something like that. There wouldn't be much point in 
showing an ETA for them.

A summary line would not be able show a reasonable ETA at all in a 
similar case. I can't remember if the older versions tried to or not but 
as you can imagine, trying to average "in two weeks" and "in 15+ years" 
will not produce anything usable.

You should be able to handle the difference with a trivial regexp though.
