Prevent foreman to crash when typo in code

I am using foreman gem on my Rails project to handle the different processes to be launched at startup (web, mailer, delayed job, ...).

It's working as expected but if I save a file with a typo or try to access a property on a nil object, foreman crash for all processes. I have to manually kill each ruby and node (for maildev) processes in order to run foreman start again.

Is there a way to prevent foreman to crash as the plumber plugin for gulp tasks ?

Thanks !

• Rails 4.2
• Ruby 2.2.0
