zram acts as a compressed block device, essentially a virtual disk in RAM. When a process needs to swap, the kernel treats swap on zram like it does on any other block device, sending I/O requests through the block layer. Importantly, once zram fills up, it's just another storage device that's reached capacity. There's no automatic mechanism to move data elsewhere, which means cold pages that were swapped out first stay locked in fast RAM with no way to evict them. As you can imagine, that's typically very bad.

The workers, running on separate threads, will use this wakeup pipe to report when they've completed a task. The event loop, over in the runtime's main thread, uses select() to monitor the wakeup pipe's file descriptor until it's ready for reading. Additionally, the earliest timer is set as select()'s timeout so that the event loop can stop waiting on the wakeup pipe and go and handle timer callbacks.。WhatsApp网页版是该领域的重要参考
