+Summary: Sharing/Access violation after exiting a running mono app with an open StreamWriter
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+Terminating a running mono process with an open StreamWriter, either by
+using kill or Ctrl-C, will cause a sharing violation on the file when the
+process is restarted.
+Steps to reproduce the problem:
+1. Open a StreamWriter and write some output to it.
+2. Kill the process while it is running
+3. Try to start the app again, and you will get something like the
+following exception
+Actual Results:
+Throws the following exception on restarting the app:
+Unhandled Exception: System.IO.IOException: Sharing violation on path 
+TestApp.log in <0x0032a> System.IO.FileStream:.ctor (System.String 
+name, FileMode mode, FileAccess access, FileShare share, Int32 
+bufferSize, Boolean isAsync, Boolean anonymous) in <0x0001f> 
+System.IO.FileStream:.ctor (System.String name, FileMode mode, 
+FileAccess access, FileShare share) in (wrapper 
+remoting-invoke-with-check) System.IO.FileStream:.ctor
+in <0x000e1> System.IO.StreamWriter:.ctor (System.String path, Boolean 
+append, System.Text.Encoding encoding, Int32 bufferSize) in (wrapper 
+remoting-invoke-with-check) System.IO.StreamWriter:.ctor
+in <0x0004a> ConsoleApplication4.Class1:Main (System.String[] args)
+Expected Results:
+Mono should have no issue re-opening the file
+How often does this happen?
+Every time.
+Additional Information:
+It only affects recent builds.  I can remember it not being an issue, until
+l about three weeks ago.
