Need suggestions for time scheduling async tasks

[void09]

Thank you for the suggestion, unfortunately the way it works is not clear to 
me, and how I should implement it for my use case. I realized the actual 
requests are done by a single procedure in my code, and I can calculate a sleep 
delay at the start of it, given the times previous requests were made and the 
ratelimit constraints. It will do. Although a more generic queue-like (outside 
of asyncdispatch) method would have been preferable.
