[sr-dev] [Async] async_sleep does not work insido a while block

[Daniel-Constantin Mierla]

Hello,

async_sleep() has some limitations listed in the readme, specifically, 
the state of config execution is lost since the resume happens in 
different application process. You better use the async_route() function 
if you are not that familiar with the internal cfg file interpreter. As 
a matter of fact, async_sleep() was added more for sampling reasons, to 
help other developers discover internal async API.

Cheers,
Daniel
