This is already with Davids fix. It only fails on Lilliput, not in head.

I only see timeouts with compiler enabled (both c1 and c2). No errors with Xint. But on both x64 and arm.

I tested with LockingMode 0 (HeavyMonitors) and 1 (default), all the same.

I debugged the app, but could see no obvious deadlock. All relevant threads were waiting on unowned monitors.

Okay, will do that.
