Suspending with Ctrl-Z freezes all controls, hard reboot required #57

Now, I know this isn't a bug, per se, but more of a lack of user fault tolerance. As a newish Linux user, as I was trying to find a way to make the process run in the background, I hit Ctrl-Z and it suspended the process. Little did I know at the time that meant everything stopped and didn't run in the background. Because everything stopped my keyboard and mouse ceased to function. I had no known way to resume the process or fully quit it, so I held down the power button to force a restart.

Is there a workaround or trick to avoid that if I accidentally do that again in the future? Maybe there's something I can include in the command to help?

I don't know if there is a possible solution based on the way this is currently implemented, but I would have expected that if the process was suspended, all keys go back to their original function. I'm very curious.

Side note: This is an awesome tool. I was fed up with Xmodmap and its complexity. I'm glad I found this.

I have done this a couple of times by mistake too. I sshed to the machine from my phone and did kill -9 on the process.

Funny, I had that happen to me when I typed Ctrl+S in the console, but I still had mouse control so I could kill the process by closing the terminal window.

I suspect the only true way to guard against this would be a separate watchdog process that kills the main one if it becomes unresponsive.

Is there any actual proposal as to how to solve this though in xkeybind itself? Seems it's just kind of a problem with using software that steals/grabs all the inputs and holds them long-term...
