+Summary: MemoryStream Position Incorrect After write
+
+MemorySteam property Position is incorrect after some writes.
+
+Test case returns this on .NET built using .NET/csc:
+memory.Postion memory position:16
+
+Test case returns this on Mono built using mono/mcs:
+memory.Postion memory position:22
+
+//
+// Mem.cs - tests MemoryStream property Postion being wrong
+//
