Pty host becomes unresponsive when creating a new terminal right after manually relaunching an existing one

[Tyriar]

Related to #117956

Repro on Windows:

1. Open a terminal
2. Type something into it
3. Toggle the auto attach value, wait for the ⚠️ icon in the terminal
4. Relaunch the terminal by hovering ⚠️
5. Create a new terminal

Shared process log when this happens:

[IPC Library: Pty Host] TRACE IPty#spawn C:\Program Files\PowerShell\7\pwsh.exe [] {name: "pwsh.exe", cwd: "E:\GitHub\microsoft\vscode-hexeditor", env: {…}, cols: 58, rows: 16, …}
[IPC Library: Pty Host] TRACE IPty#kill
WARN No ptyHost heartbeat after 6 seconds
ERR No ptyHost heartbeat after 12 seconds

I'm beginning to think this is just another manifestation of #76548

[Tyriar]

Yep, the fix for that also fixes this

This actually reproes after any manual relaunch for me ( no need to create a terminal quickly after). Just takes 10 seconds

[Tyriar]

Things I tried:

• Throttling spawn calls
• Throttling kill calls
• Throttling both spawn and kill calls, ensuring they don't happen near each other
• Ensure no kill call happens within seconds of process data events

Nothing seemed to fix it. Pushing this to May, I don't think investing more in a mitigation is worth the effort here, we should work on the actual asar fix.

Re-installing(removed VSCode from windows setting and downloaded stable version(1.56.0) from the website) VSCode worked for me

I am seeing this issue repeatedly
Version: 1.55.2 (user setup)
Commit: 3c4e3df
Date: 2021-04-13T09:35:57.887Z
Electron: 11.3.0
Chrome: 87.0.4280.141
Node.js: 12.18.3
V8: 8.7.220.31-electron.0
OS: Windows_NT x64 10.0.19041

When > 1 terminal window is open either side by side or in separate mode, or indeed on sepearte instances of VSCode.
PS I use the Terminal confgured as a git bash

I believe issue was closed for 1.54.x but see version above

I tried the latest Insider's version and the Terminal dod not open at all - completely broken.
Steps: Menu->Terminal->New Terminal
No response.

I still have on the insider build (updated June 3rd). Terminal works for a while but eventually becomes unresponsive.

Here follows my config for terminal in Windows:

 "terminal.integrated.fontFamily": "Fira Code Retina",
  "terminal.integrated.defaultProfile.windows": "zsh",
  "terminal.integrated.profiles.windows": {
    "zsh": {
      "path": "C:\\cygwin64\\bin\\bash.exe",
      "args": ["-lic", "cd $OLDPWD; exec zsh"]
    },
    "PowerShell -NoProfile": {
      "source": "PowerShell",
      "args": ["-NoProfile"]
    }
  },
