@rainers: Sorry mate, we'd need your help again for msvc_eh_terminate() adaptations with MSVC v17.10, x64 only. libcmt seems fine, libcmtd broke. No results for the dynamic variants yet, will update this comment as CI results come in.

Edit: msvcrtd is broken too, but the release one fortunately still works too. So only both x64 debug variants broke.

Hi @kinke, please try this one: #4683

A bit of a pity that lit needs an extra psutil pip package for this functionality. And hardcoding a time-out isn't ideal either, but I assume 60 secs is enough.
