CmdRunner keeps spawning new processes

[myyra]

CmdRunner with the pseudo-terminal mode keeps spawning new processes and leaving the old ones hanging around. This has made me hit the process limit multiple times.

Could you add some more information around "pseudo-terminal", please? …for repro purposes.

• What emulator are you using?
• What shell?
• Is this behind TMux?

By pseudo-terminal, I mean the pty option in the CmdRunner module. Setting pty: true causes the processes to hang around forever. Setting it to false resolves it.

I don't think that's terminal-specific, but I'm using iTerm2 3.4.14 with Bash 5.1.16, no TMux.

I thought it's because the PTY is never closed in here, even though https://github.com/creack/pty says it should be.

BUT after quickly adding defer func() { _ = f.Close() }() there, the commands are still not cleared.
