+Summary: RACE: Environment.Exit and new threads
+
+Description of Problem:
+A lot of different errors are thrown when trying to exit application 
+that's creating new threads... These types of errors depends of what 
+these new threads are busy with.
+
+Steps to reproduce the problem:
+1. mcs test.cs
+--8<----test.cs-----------------------------
+using System;
+using System.Threading;
+
+public class test {
+ public static void StartNewThread() {
+  Thread t = new Thread( new ThreadStart( StartNewThread ) );
+  t.Start();
+  DateTime dt = DateTime.Now;
+ }
+
+ public static void Main( string[] args ) {
+  Thread t = new Thread( new ThreadStart( StartNewThread ) );
+  t.Start();
+  Thread.Sleep( 1000 );
+  Environment.Exit( 0 );
+ }
+}
+--8<-----------------------------------------
+2. mono test.exe
+
+Actual Results:
+I'm getting a lot of mistakes like this:
+--8<-----------------------------------------
+Unhandled Exception: System.ArgumentException: Key duplication when 
+adding: 2005
+in <0x001d7> System.Collections.Hashtable:PutImpl (object,object,bool)
+in <0x00015> System.Collections.Hashtable:Add (object,object)
+in <0x001f5> System.CurrentTimeZone:GetDaylightChanges (int)
+in <0x0002b> System.TimeZone:IsDaylightSavingTime (System.DateTime)
+in <0x0001b> System.CurrentTimeZone:GetUtcOffset (System.DateTime)
+in <0x00064> System.DateTime:.ctor (bool,long)
+in <0x0002e> System.DateTime:get_Now ()
+in <0x0006d> test:StartNewThread ()
+in <0x00041> (wrapper delegate-invoke) 
+System.MulticastDelegate:invoke_void ()
+--8<-----------------------------------------
+
+Sometimes the application just hangs on...
+
+What's interesting, if I replace the string 'DateTime dt = DateTime.Now;' 
+with the following line:
+IPAddress hostadd = Dns.Resolve( Dns.GetHostName() ).AddressList[0];
+then I'm getting the following error:
+--8<-----------------------------------------
+[vadim@skif testexitwithnewthreads]$ mono test.exe
+
+** ERROR **: : EnterCriticalSection failed: Invalid argument
+aborting...
+Aborted
+--8<-----------------------------------------
+
+Expected Results:
+Should work OK with Mono, as it's working well on MS.Net.
+
+How often does this happen? 
+Always
+
