- * Applications that dynamically allocate lots of small strings
- * run the risk of significantly fragmenting the heap. This module
- * aims to reduce this risk by allocating large arrays of small fixed
- * length strings, arranging them as a free-list and allowing
- * callers to allocate from the list. Strings that are too long
- * to be allocated from the free-list are allocated from the heap.
- * Since typical implementations of malloc() eat up a minimum of
- * 16 bytes per call to malloc() [because of alignment and space
- * management constraints] it makes sense to set the free-list
- * string size to 16 bytes. Note that unlike malloc() which typically
- * keeps 8 bytes per allocation for its own use, our allocator will
- * return all but one of the 16 bytes for use. One hidden byte of overhead
- * is reserved for flagging whether the string was allocated directly
- * from malloc or from the free-list.

-/*
- * Set the length of each free-list string. The longest string that
- * will be returned without calling malloc() will be one less than
