The program doesn't exit after downloading the OS

This doesn't happen on master but happens with #453

There are 3 objects holding the process from exiting.
Two are process.stdin and process.stderr. Unrefing them removes them from the process._getActiveHandles(). The third one is a timer with the method called listOnTimeout coming from the timers module.

So this looks like some of the newer dependencies may be holding the process, and I assume the SDK is the suspect as it used to hung my tests locally, but I can't localize it yet.

Looks like it's the memoizee's maxAge (which I've been able to trace with https://www.npmjs.com/package/wtfnode): medikoo/memoizee#25

Closing here and will resolve in the SDK.
