Description

The following code leaves ghost processes running after exit on Linux:

$ autocannon -d 20 -c 100 http://localhost:3000/a & autocannon -d 20 -c 100 http://localhost:3000/b & autocannon -d 20 -c 100 http://localhost:3000/c

This happens both when interrupted (C-c) and after finishing. Observed in both Fish shell and Bash.

Contributor guide

Research direction
Investigate how autocannon manages child processes when multiple instances are chained with `&` and ensure proper cleanup on exit or interruption.
