Description of Problem:
FileStream.SafeFileHandle is un-impl'd, see output for example. this occurs in
the release version of 2.4.2.3

Steps to reproduce the problem:
1. in booish.exe (Boo interactive shell)

>>>import System.IO
>>>file = File.Open(path, FileMode.Open)
System.IO.FileStream
>>>file.SafeFileHandle
System.NotImplementedException: The requested feature is not implemented.
  at System.IO.FileStream.get_SafeFileHandle () [0x00000] 
  at Input5Module.Main (System.String[] argv) [0x00000] 
  at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke
(object,object[],System.Exception&)
  at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags
invokeAttr, System.Reflection.Binder binder, System.Object[] parameters,
System.Globalization.CultureInfo culture) [0x00000] 
>>>



Actual Results:
see about stack trace

Expected Results:
to not explode

How often does this happen? 
every time

Additional Information:
this is a blocking issue.. I actually discovered this when trying to use
csharp-sqlite (a managed implementation of sqlite 3,
http://code.google.com/p/csharp-sqlite/) ... the full stack trace from
csharp-sqlite (with whom I also filed a bug) is:

Unhandled Exception: System.NotImplementedException: The requested feature is
not implemented.

CS_SQLite3.sqlite3& ppDb) [0x00000] 
  at CS_SQLite3.SQLiteDatabase.OpenDatabase (System.String DatabaseName)
[0x00000] 
  at CS_SQLite3.SQLiteDatabase..ctor (System.String DatabaseName) [0x00000] 


.. anyways, the csharp-sqlite code works fine in windows/ms.net .. I suppose
there's some block of un-impl'd functionality and FileStream.SafeFileHandle's
current status is just a symptom of that. Is it possible that this could be
rectified? if so, I would really appreciate it.

Thanks
