Summary: System.IO.MemoryStream is too eager in zeroing data
Product: Mono: Class Libraries
Version: 1.2

When a MemoryStream that was created around an array is shrinked and the
expanded, it should no longer allow access to the elements that were present in
the array before the shrink. However, MS.Net MemoryStream does this by zeroing
the underlying array when the expansion is performed - mono clears the array
on shrink. This is somewhat of a corner case, but the behaviour differes none
the less. Also, clearing on expansion improves performance a bit (well, at
least when the MemoryStream is only shrinked - it changes nothing when a
shrink/expand cycle is performed). A test case (passing on MS.Net) is attached.
