Re: [SR-Users] async workers

The workers defined by async module are only for that module and used only by async_route() and async_sleep(). The implementation is also different, the async module workers are more like timer processes (because both of async_route() and async_sleep() need to sleep some interval of time). The module itself keeps the lists of tasks in a structure optimized for timer execution. Each of this async module workers check from time to time to see if there is a task to be executed, executes what matches the time, then sleeps again for 100ms (iirc), then checks again... The async_workers from core were designed to receive the job immediately. Because of that, there is an interprocess communication based on sockets in memory. The async workers are listening on them, so once a sip worker sends the task to them, an async worker will receive it.
