@superlopuh what was the need for this? my issue is that using that default locally causes some tests to timeout, leading to the inability to generate a coverage report.

The quickest workaround would be to pass the timeout in the Makefile from the environment and use lit's --timeout option.
Would it be OK if I open a PR with this?

[superlopuh]

If we need more time then let's add more time, we do want a timeout though because some things have taken infinity time in the past.

[superlopuh]

BTW I think we can safely remove the timeout in the makefile, I forgot to do that in this PR

yeah, I know, it's inconsistently used in the current rules. The cmd line option overrides the lit configuration, so I'm happy to use it as such.

I'll fix it in a wee PR.
