Hey, Vitaliy!

I know, right?  All programming textbooks say: "sleep() is bad", "Avoid 
synchronizing with sleep()", "sleep() is hackish", etc.  But, for this 
use case, async(sleep()) helps you achieve this zero-cost polling loop, 
which almost feels like magic!  To me, it looks like the ideal 
solution.  Also, for more precision, you can use async(usleep()).
