Description

Type: Bug

Every terminal starts with the following message before the first prompt:

bash: cannot set terminal process group (8590): Inappropriate ioctl for device
bash: no job control in this shell

I thought it was related to issue #181939 but it's still present.

It prevents ctrl+C out of long-running processes, and other similar commands. If a process is running when the window is closed, CodeHelper crashes.

Research direction
Investigate the interaction between VS Code's terminal process and macOS shell job control. Review comments in the issue and related issue #181939. Examine the terminal source code in src/vs/platform/terminal/ and the node pty library to understand how process groups are created. Check if the issue is related to Electron's child process handling or the specific macOS version.
