Thermopylae
When the Kernel wrote again, 'Hand over your system resources', the Program wrote in reply 'Come and take them'.
You can't always win, but you can always make them SIGKILL you.
Usage
All you have to do is require "thermopylae" and your program will stubbornly refuse to exit. thermopylae registers a signal handler for every signal that the ruby VM will permit it to "IGNORE". If you wish to restore the default behaviour you can call Thermopylae.submit_to(signal_name), but this is of course not recommended.
Caveats
Worth noting that all the defenders at Thermopylae died painfully...
