I think the key was the "if there is enough memory" - which I think is
a pretty big issue.  Running 25 invocations of java each wanting
100-200MB of RAM will cripple a system relatively quickly.  And 25
really is just scratching the surface when most people think
"cluster."

I think the only way to really fix this would be to integrate
distributed behavior into make itself.
