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

And if I replace the line 'DateTime dt = DateTime.Now;' with
'string command = Environment.CommandLine;' then I'm getting the 
following errors:
--8<-------------------------------------------
[vadim@skif testexitwithnewthreads]$ mono test.exe

** ERROR **: file critical-sections.c: line 172
