ptyHost process has memory leak

[ztsing]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: Version: 1.68.1
• OS Version: Windows_NT x64 10.0.19043

It seems like a memory leak

The memory usage grows from hundreds of MB to more than 4000 MB in one night.

@ztsing can you share your settings.json file?

@ztsing can you share your settings.json file?

I open multiple vscode windows and some of them in remote-ssh mode.

interesting

"terminal.integrated.persistentSessionReviveProcess": "never",

It still needs to keep the serializer around for reconnection. It's possible this is an issue in conpty, I've never noticed it go very high on my machines.

I remove this setting item. However, the problem still exists.
