Implementation can't create 10000 threads

I ran the following program which keeps all the threads until everything is 
done. For N =10, 100, 1000, the program ran in 11, 74 and 352 msecs. It has not 
terminated in 20 min for N = 10,000.

valN=10**4

defspawn(0)=0
defspawn(n)=(x>>n)<x<spawn(n-1)
spawn(N)

At one point in the Orc 2.0 release, I successfully tested 1000000 tokens.  
Tokens or Groups may have become too heavyweight.

This appears to be a threading issue, not an allocation issue.  The example (N 
= 10**4) results in java.util.concurrent.ThreadPoolExecutor creating 451,997 
java.util.concurrent.locks.AbstractQueuedSynchronizer$Nodes, when polling the 
queue for new tasks.

[previous, now deleted, comment about thread creation was erroneous.]

With the optimizations added in r2897 through r2908, and a bigger heap, this is 
fixed.
