100% CPU utilization while idle

[123vivekr]

I've noticed the program uses 100% of one of the 4 CPU threads while idling without any tasks. This seems like a bug which needs to be looked into.

Can confirm this is an issue ( persists when running server with more workers ). I'll try to profile parseable to see what is causing this but most of the code is async and thus idles correctly. The noticable culprit could be spin loop check on localsync which runs the schedular.

In addition to this opening two more issues related to resource utilization.

The issue arises from usage of clockwerk::AsyncSchedular in a dedicated runtime. The runtime has only one task that is to poll this future and thus it causes 100% usage on whatever thread it is running on.

We can look at https://github.com/lholden/job_scheduler as a viable alternative.
