This is a ringless implementation of millisecond precision timer and millisecond async_sleep function. I've added the functionality to the current async mod but this can me moved to a dedicated module. For now only the async_ms_sleep is implemented but async_ms_route is just a few lines. Anyway how should I proceed with cleanup so this can be accepted ? With millisecond precision sleep one can easily implement a leaky bucket request shaper that delays incoming requests to achieve perfect rate limits per customer/sip-trunk/whatever without dropping requests. No more spikes and no more 503s. I've implemented external HTTP microservice that returns millisecond delays per dialog initiating request and tested it with SIPP with 3 flows/streams each with 250 CAPS. No leaks nor other issues in 24hrs of testing.
