nodes with no parallelism were being dropped from the plot
make sure escaped filenames fit in a reasonable file size
when a reduce on a long list of files fails, do not print the whole list
portability fix
bugfix: redistribute was going to multiple destinations and not caching lookups
use rsync -u so if there are conflicting versions of files laying around we always take the newest.
bugfix: free memory estimation was wrong
better logic about when there is enough memory to run more.  We were making single-node machines run with no parallelism
since redistribute does n=1, reduce operations should too
allow a map command to start with a redistribute (a "<")
regression: stopped supporting nodes that do not have hostnames (local nodes)
first steps to using a single remote shell to launch multiple schedulers on that host
