Overview

Pool for ELF files.

This pool is useful for tools that recurse over a tree of dependencies to avoid creating multiple instances of Elf::File being open and accessing the same file.

Notes:

- Instances might be re-created if no strong references left to specific
  Elf::File
- New instance will be created on access if previous one were closed
