With mine too and I would presume everybody else's.  I've been
annoyed for a long time by one of those sharded Meson-Win test jobs
that hang around until timeout.

Thank you very much for addressing the issue.

Interesting.

So another viable fix (no, I am not suggesting a counter-proposal,
but asking a pure question to see if I understand the issue
correctly) is to rewrite "assert(cond)" to "if (cond) BUG(...)"
or something like that, so that it truly fails?

OK.
