Note that the static parameter won't greatly improve the speed of example2.

This is because these arrays are only 3 or 4 elements deep, but there are 500 arrays to be watched.  The static parameter will speed up the watching of each individual array, but the overhead for watching multiple arrays scales O(n) where n is the number of arrays.

The static parameter best helps performance when there are very deep arrays, as in the case of the new hugedata example.
