I have a very large codebase that fires the odd ResourceWarning, and after 
fixing them all I'd like to ensure that they do not reoccur. When using `-W 
error` it still won't fail CI. So I would use this -X option for more than 
debugging user extension modules

It looks like a good idea to me. But it should not be -W error. It should be an 
-X option, and this option should be used exclusively for debugging user 
extension modules.

Hi Serhiy,

What do you think about this idea?

Normally, we could use -W error when there is an exception.

[issue36829] CLI option to make PyErr_WriteUnraisable abortthe current process

New submission from Thomas Grainger :

Currently it's quite easy for these errors to go unnoticed.

I'd like a way to easily detect these in CI.

nedbat suggested piping the process output to another tool, and looking for 
'Exception ignored in:' but this seems a little diff
