 and it will sleep for the full 4 seconds.
 Btw, DateTime.Milliseconds returns "the milliseconds component of the
 date represented by this instance", ie a value between 0 and 999, not
 the number of milliseconds since the epoch.  For that you need a new

+If it's by design, that's IMO not the most fortunate design. This
+issue bit me in the following scenario (simplified):
+while (true) {
+  Thread.Sleep(3*3600*1000);
+  InvokeBigMaintenanceTask();
+Now, if I use SIGQUIT to inspect the process'es state, the maintenance
+task gets invoked very prematurely, doing many things I didn't want to
+yet done (thus the 3h sleep) and mangling the very state I was trying
+to observe with SIGQUIT.
+I worked around this by reissuing the sleep if it, for whatever
+OS-related reason, returns earlier than expected (as determined with
+DateTime.UtcNow). However, I would expect the runtime to do that for me.
+Also please note that the current behavior doesn't match the
+documented behavior of either SIGQUIT (according to the man page) or
+Thread.Sleep. So IMO if it's not addressed otherwise, this behavior
+should be documented.
