+Summary: Timer not calling callback when dueTime = 0 and period is Timeout.Infinite
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+When a timer is changed to go off immediately with a call to "Timer.Change
+(0,Timeout.Infinite)" the callback does not get called. This works 
+in .NET 1.1.
+
+Steps to reproduce the problem:
+1. Execute the following test: mono TimerTest.exe
+2. 
+3. 
+
+Actual Results:
+
+The callback does not get called so the console only shows:
+
+Press Enter to exit.
+
+Expected Results:
+
+Expected to get the output from the callback :
+
+Callback called
+Press Enter to exit.
+
+How often does this happen? 
+Always.
