We must also inspect the diff between upstream vs generated certificate. We must try to copy as much information as possible in generated certificates. E.g. list of all common names.

@lubosmato Thank you for digging into it. One of the reasons I never enabled `--threadless` as default due to lack of testing across OS (especially Windows). IIUC, this is a...

PS: It's about a month I am running `proxy.py` locally on `macOS BigSur` with `--threadless`. I haven't observed anything noticeable. Only occasion when I had to stop `proxy.py` was while...
