* The purpose of this structure is to replace dynamic memory allocations,
* because we target architectures where this may not be available. It is
* essentially a resizable (within specified parameters) block of bytes,
* which is initially created either by memory allocation or TODO as a pointer
* into some fixed rewritable space.
*
* Unlike the context object, this cannot safely be shared between threads
* without additional synchronization logic.
