Async Allocators: A Paradoxical Concept

Making allocators asynchronous presents a fundamental dilemma, characterized as a 'bad great idea.' The proposal suggests that while the concept is theoretically sound, its practical implications make it cumbersome. In Rust, the traditional allocator interface relies on immediate responses for memory allocation, unlike in environments such as embedded systems, where memory management can be more complex and limited. The podcast highlights the challenges faced with current synchronous allocation patterns, particularly in scenarios demanding flexibility, like under memory constraints.
