Thanks for posting these profiles, this is done with

Also, I noticed that you have code like this:


I would prefer if you swapped the code, so it reads:

That memory consumption apparently comes from:   

116 KB Mono.Globalization.Unicode.MSCompatUnicodeTable::FillTable(BinaryReader,byte[]&)
     116 KB        5 System.Byte[]                                   

Which am confused, I cant find that signature, I find:

	static void FillTable (PtrStream s, ref byte* bytes)

And thanks for catching the new UnmanagedMemoryStream class ;-)
