+Summary: System.Random().Next() and System.Random().NextDouble()  generate the same consecutive random numbers
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing. 
+Description of Problem: 
+ 
+when generating lots of consecutive random numbers Next() and NextDouble() 
+generate the same number.  Here is some nemerle code: 
+ 
+using Nemerle.Collections.List; 
+using Nemerle.IO; 
+ 
+def random(times, acc) { 
+   match(times) { 
+      |0 => acc 
+      |t => random(t - 1, System.Random().NextDouble()::acc) 
+   } 
+} 
+def randlist = random(100, []); 
+Map(randlist, fun(a) { print("$(a)\n"); }) 
+ 
+Steps to reproduce the problem: 
+create a list of numbers in a loop with System.Random().NextDouble() 
+print the list 
+ 
+Actual Results: 
+large consecutive chunks of numbers are the same 
+ 
+Expected Results: 
+each number should be different 
+ 
+How often does this happen?  
+every time 
+ 
+
