> There are several places where an array of ints gets added to an int vector, 
> by iterating over the array, and calling the add(int) method.  This can be 
> improved by having a bulk add operation that does various growing/bounds 
> check just once, and then does the copy using System.arraycopy.  This has a 
> measurable effect (not too much, but observable) on things such as CAS 
> serialization.
