Detailed Description

Allocator is a bump-pointer allocator with an SPI for getting more memory from embedder-implemented allocator, such as malloc()/free().

allocations never return NULL. The implementation of allocChunk() is expected to perform a longjmp or exception when an allocation can't proceed.
