Issue

Fairly easy to reproduce, when I'm looking through say our elk stack and trying to find out what happened to logstash and looking through log files, catting those through hyper slows it to a crawl and it's unable to keep up with the output and locks up the terminal where I have to either wait for 2-3 minutes or force quit out of the application.

I tried moving to canary to see if it was addressed there and it's not.

Start by reproducing the slowdown in vanilla Hyper.app on macOS High Sierra 10.13.1 with a command such as cat streaming log output, using the reported Hyper 2.1.1 canary version. Done means Hyper keeps up with the output without locking the terminal or requiring a wait or force quit.
