 Could you break down the description?
 I don't know EM::Synchrony.
 
 Why you need to choose root or not root?

 Since the root fiber is treated differently than other Fibers (e.g. you can't yield from the root), code which can optionally use fibers for high-performance IO (in my case, the Mysql2 driver) needs Fiber#root? to know when it can use Fibers to execute a query versus using a standard blocking call.
