Detailed Description

Copyright (c) Theophilus Eriata. All Rights Reserved.

Low-level memory allocator that manages whole memory pages from the operating system.

This allocator requests memory directly from the OS in page-aligned chunks, typically 4KB or larger. It's designed for scenarios where you need large, aligned memory blocks with minimal overhead. Unlike general-purpose allocators, this operates at the virtual memory level and may reserve address space that isn't immediately committed to physical memory.

Use this allocator when:

• You need very large memory blocks (typically >64KB)
• Memory must be page-aligned for specific algorithms or OS APIs
• You want to minimize memory overhead for large allocations
• You're implementing higher-level allocators that need backing storage
