"If for some reason a capacity of 32,767 is insufficient, you can trivially upgrade your queue to an Enterprise Queue"

I’m confused by the infinite « while » : is it a common pattern of lock-free data structures ?

Do you mean this part

“This is a busy-wait loop, which makes for a simple illustration but isn’t ideal. In a real program I’d have the producer run a job while it waits for a queue slot, or just have it turn into a consumer (if this wasn’t a single-consumer queue)”
