Mono Issues

POST with HttpWebRequest is leaking memory -- probably in WebConnectionStream

http://bugzilla.novell.com/show_bug.cgi?id=397627

Note: This leak is critical to us when using the S3 storage provider!  After much debugging it looks like the HttpWebRequest and WebConnection objects are being release but the GC isn't collecting the byte[]'s used by these objects.  If you force a GC.Collect() some (though possibly not all) memory is freed.
