Luke De Feo 862592e03d Account for race conditions with stream intercetor ...

Summary:
Given that stream interceptor is async the folling race conditino could occur.

Frame at time t=0 comes in, we yeild to the event loop while fetching metadata, fetch takes 5 ticks

Frame at time t=1 comes in, we yeild to the event loop but fetch takes 1 tick

At time t=2 the second frame is augmented  and display

At time t=5 the first fetch returns and we display and older frame

This is a simple check to avoid this.
