Hello, I am on Debian and have following packages installed. I am using zsh, and there was no problem yesterday, today is like this, I run some program, and I cannot CONTROL-C neither CONTROL-Z and terminal waits for something very very long time. This happens only 1-2 times with 1-2 commands in terminal, later it gets liberated.
