The problem is that the fact we want the ieframes.dll implementation and 
none other is absolutely not documented currently. Just relying on the 
test executable's name is insufficient imho, especially as it runs 
counter to the COM philosophy[1]. Similarly, relying on WineTest or 
Testbot 
behavior is insufficient in this case.

So I think it owuld be much better if the test itself documented what 
its requirements are, either with a LoadLibrary() or with at least a 
trace or comment in the code.


[1] That is, the fact that a piece of code tries to create a 
CLSID_WebBrowser object does not imply that it wants ieframes.dll or any 
other specific dll.
