+Summary: Socket.Select fails if one of its ILists is empty.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+Socket.Select fails if one of its ILists is empty.
+
+Steps to reproduce the problem:
+
+Pass Socket.Select an IList which refers to an empty collection.  You could
+pass Socket.Select no file descriptors at all; for example:
+
+Socket.Select (readers, null, null, 1000000);
+
+where readers is an empty collection.  Alternatively you could give it some
+file descriptors but with one empty list:
+
+Socket.Select (readers, writers, null, 1000000);
+
+where readers contains a number (> 0) of file descriptors, while writers is
+empty.
+
+Actual Results:
+
+A null reference exception is thrown.
+
+Expected Results:
+
+Socket.Select should regard the empty IList as simply passing no file
+descriptors.  If all the lists are empty, it should delay for the time
+given in the last parameter, then return.  If some lists are non-empty, it
+should regard the empty lists as equivalent to passing null.
+
+How often does this happen? 
+
+Always.
+
+Additional Information:
+
+This bug occurs with beta 2.
