Description

WaitHandles don't seem to wait.

Repo:

var t = new AutoResetEvent (false);
var rv = t.WaitOne (30000);
Console.WriteLine (rv);

this finishes immediately, printing false.

This happens in the iOS simulator (it does not happen on macOS)

Regression?

Yes, it regressed between 6.0.100-preview.3.21161.23 and 6.0.100-preview.3.21172.2.
