Threading limits

[Bevan C. Bennett]

Ah... thanks! That indeed appears to be the main issue.
The difference between the two systems is a different default stack size!
Using 'uname -s 1024' allows both to get just over 3000 threads off.

Getting back to the Java, tweaking -Xss looks like it should help take 
care of things.
