Good afternoon,

In using the provided reproducer, on an updated system, I am unable to encounter the same endless hang condition. Would it be possible to confirm if the same issue is still observed with the latest systemd revision available?

@kwalker: It helps if the system is under heavy CPU load. Then I can get the hang in a few dozens of iterations.
