@rayegun I am not sure if this is right. I couldn't find cholmod_common_l anywhere.

Yeah that's just to ensure they stay separated.

What was this PR for? Oh error message nevermind.

Finished a paper deadline so I'll go through and try to clean things up

[ViralBShah]

I was looking for anything that might help resolve the threaded tests that fail in github actions. They don't fail on the julia buildbots but they always fail in github actions - and I was wondering if that was a real bug on our side. Specifically making sure that structs are correctly created and mirror what CHOLMOD expects (no overflows, etc.).

[rayegun]

Can you point me to the logs that fail? Is it just the GAs in this repo?

[ViralBShah]

Yeah, see the failing windows tests in the CI right here in this PR. It times out in the threading tests.
