You probably knew this but just in case the term for this strategy is called a "ripcord allocator". I believe GCC had one, not sure if it still uses it. I doubt any existing ones are especially helpful though compared to looking at regular allocators and seeing how to integrate them. I assume you're also aware of lock-free data structures and the like. A memory allocator seems like something that needs to be super aware of causing concurrency bottlenecks since it has no idea where it'll be used. -- greg -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
