That also means that applications can't depend on this behaviour, since
the behaviour is different across platforms.

That's simple, you haven't listed a single application affected by this bug.
Any other bug with 100% cpu usage needs its own investigation.

Then this bug could be closed as a WONTFIX. You have found something that
doesn't exist anymore.
