Could you build this?
No Creating a transparent persistence engine that provides a seamless, infinite-RAM illusion for Python objects requires sophisticated low-level virtual memory manipulation, custom allocators, cache-eviction strategies, and deep runtime interception.
What it would actually take: A real implementation requires C/C++ or Rust bindings into Python's CPython internals, managing memory-mapped files (mmap) or custom paging daemons. The engine must track dirty pages, handle pointer swizzling/serialization on the fly, and resolve page faults without corrupting Python's reference counts or GC. This demands deep systems programming expertise and intimate knowledge of Python internals.
