+Summary: Dns.GetHostName and Environment.CommandLine problem
+
+Description of Problem:
+On Mono 1.1.3 when parameters are specified for command line the call of 
+Dns.GetHostName() destroys the Environment.CommandLine environment.
+
+Steps to reproduce the problem:
+1. mcs A.cs
+--8<-----A.cs----------------------
+using System;
+using System.Net;
+
+public class B {
+ public static void Main( string[] args ) {
+  Console.WriteLine( System.Environment.CommandLine );
+  string hostName = Dns.GetHostName();
+  Console.WriteLine( System.Environment.CommandLine );
+ }
+}
+--8<-----A.cs----------------------
+2. mono A.exe 35 /np 1
+
+Actual Results:
+You'll see something like that:
+--8<-------------------------------
+/home/vadim/mcsharp2/A.exe 35 /np 1
+And then some garbage is printed until you press Ctrl+C...
+--8<-------------------------------
+
+Sometimes it throws exceptions like this:
+--8<-------------------------------
+Unhandled Exception: System.NullReferenceException: Object reference not 
+set to an instance of an object
+in <0xc7a61a27> (wrapper managed-to-native) System.String:InternalJoin 
+(string,string[],int,int)
+in <0x00004> (wrapper managed-to-native) System.String:InternalJoin 
+(string,string[],int,int)
+in <0x000f6> System.String:Join (string,string[],int,int)
+in <0x00045> System.String:Join (string,string[])
+in <0x00015> System.Environment:get_CommandLine ()
+--8<-------------------------------
+
+Expected Results:
+It should print the same lines
+/home/vadim/mcsharp2/A.exe 35 /np 1
+/home/vadim/mcsharp2/A.exe 35 /np 1
+
+How often does this happen? 
+Always
