* will be needed to prevent frequent reallocations during growth.
*
* The array grows by DEFAULT_GROWFACTOR aka 20% whenever it overflows. By
* setting the factor to 0 it will still clamp to 1 and instead grow the
* array by one slot at a time. This is not ideal but given a pooled memory
* manager you will not thrash memory too much since you will grow inside
* each pool chunk and only reallocate when switching pools.
*
* Naming of CArray instances are used to enable memory tracking of arrays
* that have gone berzerk or less frequently used instances that could be
* released after usage.
*
* The FOR_ARRAY macro is the preferred way to process all array slots.
