 Is there some way I can modify the timer class to trap the offending
 thread to see what the timing is that causes the issue? Could there
 still be a race in the timer?

+I ran some test on the MS.NET runtime. It's definitely not
+thread safe. I was able to reproduce the same races like
+in Mono.
+
+Maybe you're locking on the wrong object, or not locking
+at all at some places.
+
+Note that inserting a null check at line 192 of Timers.cs
+won't fix anything. It would hide (not cure) a race generated by
+the Timer's consumer.
+
+Chris, feel free to reopen the bug, if you have a test case.
