The other thing is Java doesn't necessarily use threads like a normal
system.  if you ever run a java vm, take a look at the processes it spawns
off.  There are like 10 processes initially java spawns off, which (I'm
not sure, as I don't have the source or know much about the actual
VM) probably means it's a separate process for each thread.  Linux handles
that perfectly fine.  I've got both processors on an old BP6 running at
around 100% utilization from two separate seti instances.
Cheers!
