   Good idea to use some form of exponential or other backoff. However, perhaps leverage `backoff`, as it's already in the python deps. If Presto can handle shorter polling intervals, why not. But that discussion needs to be resolved on `PyHive`. @bkyryliuk thoughts?
   
   Having said all this, while unnecessary waiting should be avoided, I'm personally of the inclination OLAP-type queries are ok to take a few seconds. As I expect people will tend to be hitting fairly expensive queries through SQL Lab, waiting for a few seconds for something that completed in 0.1 seconds, and conversely waiting 32 seconds for something that took 30.1 seconds, usually isn't that big a deal for me. Especially if it can spare a busy db some unnecessary load.
