Is Parallel Programming Hard, and, If So, What Can You Do About It? v2023.06.11a
GCD/libdispatch is a fantastic approach to concurrency and you can build and install support for non-Apple operating systems:

Here’s a simple echo server:

Cross-platform I/O built on io_uring and kqueue (in TigerBeetle)
One of the reasons is that libdispatch's I/O functions introduce extra dynamic allocations for internal queueing via `dispatch_async` ([0],[1],[2]) and from an API perspective of realloc-ing ([3]) an internally owned ([4]) buffer.
TigerBeetle, on the other hand, statically allocates all I/O buffers upfront ([5]), treats these buffers as intrusively-provided typed data ([6]) (no growing/owned buffers), and does internal queueing without synchronization or dynamic allocation ([7]).
