Well, no, that's the nature of dlls though. There's no guarantee that if an
app supplies one to override a system dll it will make anything run any
"better" than the system dll.

However the app that supplies a dll most certainly expects it will get that
dll, including whatever buggy behaviour it contains and may indeed rely
on to work, which is why Windows lets the app hang itself with its own
rope and looks there first.
