+Summary: memory leak in Regex.Match when using Mono on Windows
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+whenever i run Regex.Match in Mono on Windows, the mono process will
+increase it's memory usage.  In an application that uses regular
+expressions a lot, this bug makes the application virtually unusable 
+Steps to reproduce the problem:
+1. run the following code in Mono on Windows and you can see the memory
+usage going up in the task manager (it will keep going up as long as the
+program runs)
+using System;
+using System.Text;
+using System.Text.RegularExpressions;
+using System.Threading;
+class MainClass
+      public static void Main(string[] args)
+      {
+              Match match;
+              string strPattern = @"\w \w \w \w \w: \d";
+              for (long i=0;i<50000;i++)
+              {
+                      string strTest = "This is a simple test: " +
+i.ToString() ;
+                      match = Regex.Match(strTest,strPattern);
+                      Console.WriteLine(i);
+                      Thread.Sleep(10);
+              }
+      }
+Actual Results:
+memory usage keeps going up while it shouldn't
+Expected Results:
+sane memory usage
+How often does this happen? 
+every time (on windows)
