Because the only thing I want to see fixed at this point is a view leak,
it's still better than current state of things.

Without this fix Wine shows exactly the same broken behaviour as NT4 does in
the loader test when LoadLibrary is called on an already mapped image:
dangling/leaked file handle, inability to overwrite/delete an executable file.
