Should this go into `ModuleList::GetSharedModule()` or at some function that is called by `ModuleList::GetSharedModule()`? If the `ModuleList::GetSharedModule()` function is really quick, I hate to add really spammy progress notifications that aren't useful. If there is code down in `ModuleList::GetSharedModule()` that locates an external symbol file, then the progress should go in that function that is known to take some amount of time, but not here in a general area IMHO
