Yes, but marshaling an IntPtr doesn't require copying the entire buffer.
Marshaling as a System.String *does* require copying the entire buffer.

4 bytes is clearly less than 100kB+. :-)

So unless you really need a System.String, you could instead use IntPtr
and use the System.Runtime.InteropServices.Marshal methods to interact
with the unmanaged string, or you could use unsafe code and cast the
IntPtr to a byte* for memory manipulation...
