So I wanna make it default. It will be breaking but MJIT.pause is not released anywhere. RubyVM::MJIT.pause RubyVM::MJIT.pause(wait: true) # Wait only for a currently-compiled method, and pause MJIT worker immediately (the current behavior). # This will be convenient when there are many methods, like on Rails.
