We had to arbitrarily pick a number for the timeout we use to let the pre-rendering offliner do its job.  We should use data to tune this to the best number.  

For instance, we might use a 2G impairment network to access many popular websites from India or Indonesia, find the average, 90%, and 99% load times, and use that to tune this number.

We might also want different timeouts depending on whether we are on 2G or 3G or WiFi.
