iTerm2 occasionally using a lot of CPU
Every so often iTerm2 will suddenly start using 100% or more CPU.
Up until now I had a vague feeling this was after it asked me to do an update and I said yes and it restarted itself. I have just been quitting and restarting it manually again to fix it.
But it just started using 100% CPU when I definitely didn't do an upgrade, this is the second time today. It lasted for maybe 5 minutes (certainly long enough to send the laptop fan crazy) while I have been writing this issue and has now gone back to normal without a restart.
