Re: Safe handles and Marshal class

Ideally SafeGlobalMemoryHandle class is introduced in the framework and Marshal class (and any other framework class working with native memory) are extended to work with SafeGlobalMemoryHandle.

Until then I am going to do something similar to what you suggested.

possibly a good optimization; but SafeHandle also has a SetHandle

I'm curious, how do you use a global memory handle without exposing the
handle publicly?  I was assuming "SafeGlobalMemoryHandle" would used for
things like SetClipboardData and DocumentProperties where the typical
usage is to pass the handle around--but you want to ensure the handle is
freed more deterministically.
