Sylvain,

These 2 parameters are confusing to me.   --collectorLimitTreeSize
sounds like it limits the tree size to whatever your setting are,  but
so does  --limitTreeSize.     What is the difference between a tree and
a collector tree?   

I assume the collector is a garbage collector of some sort?    My guess
is that the collector limit is the largest tree allowed after collection
and the --limitTreeSize is how big it must get before collection?
