Very high CPU usage when piping

[widogg]

Hi! First time user, I just found this (pretty cool) tool and started using it right away.

I noticed a high CPU usage, which I think might be related to #17.

I'm using dpkg.log here as an example, but happen with other files too. When I do tl /var/log/dpkg.log, I have very low CPU usage and I can see the app normally, like this

However, if I do cat /var/log/dpkg.log | tl, I get a very VERY high cpu usage

Sorry the command is not fully displayed, but it definetly running tl here.

Also, I have to double ctrl+c to exit, which throws this error
