01:11 PM Ruby Misc #14222: Mutex.lock is not safe inside signal handler: what is?
- Few more questions: is adding key to hash safe? Pushing variable to array as used in http://www.mikeperham.com/2013/02/23/signal-handling-with-ruby/ ?

- What IS the recommended way to fix this if Mutex nor Thread are safe in signal handler? Also created question for what is safe in signal handler in general as #14222
