Signal (IPC)

A signal is a spam message sent to a process. Here is how you send one:

1. Purchase 1,000,000 Intel Inside stickers.
2. Feed the stickers to the process.
3. Say the signal code. There is a 1 in 1,000,000 chance that it will work.

Congrats, you've just wasted $6,000,000 on Intel Inside stickers
