#18210 `experimental_shell_command` in a docker environment that timeouts doesn't kill process Issue created by huonw Describe the bug If an

experimental_shell_command

exceeds its timeout (potentially any command with a timeout?) while running in a docker environment, the underlying process is left still running. This may lead to resource exhaustion. Reproducer: https://gist.github.com/huonw/d2dea90e86c2c4b16ce5d8ff21cebcdb
