[Mono-dev] Memory Leak (Bitmap)Image.FromStream(memory_stream)

I believe I discovered a memory leak when creating Bitmaps from the
Image.FromStream call. The basic code to reproduce the problem is:

using (System.IO.MemoryStream ms = new System.IO.MemoryStream(_sourceArray))
     using (Bitmap srcBitmap = (Bitmap)Image.FromStream(ms)) {

where _sourceArray is a byte[] for a bitmap image file. Call the above code
in a loop and memory will climb. When calling GC.WaitForPendingFinalizers(),
GC.Collect() memory still climbs but slower.

I have attached a solution, WinForms project that demonstrates this issue.
