A walkthrough of how Haiku's virtual memory subsystem fits together: the core objects, ownership, intrusive linked lists, wiring, area cutting, the arch-independent / arch-specific boundary, copy-on-write, and page-out.
All file/line references point into the Haiku source tree.

A specification of the on-disk layout of BlackBox Component Builder object code files, as produced by the Component Pascal compiler's object emitter and consumed by the dynamic module loader.
One .ocf file holds exactly one compiled module: its executable code, its
statically initialised data, its runtime meta-information (type descriptors,
export directory, debug references), the relocation information needed to place
it at an arbitrary address, and the list of imports that must be resolved before
