>> Among other things, this approach makes it easier to force the loading of a module with mismatched symbols, should anybody be unwise enough to attempt such a thing.

--Is it just me, or does this strike anyone else as a potential problem?

1. Root is the only one that can/should load modules
2. Modules with mismatched symbols act unpedictably(?)
3. This fix sounds like modules will have (at least a temporary) higher memory-usage requirement than 2.4.

--Please feel free to correct / educate me here...

Sometimes you know that a version mismatch doesn't matter. Yes, it is rare... it is much more likely that a version mismatch would cause unpredictable problems. But since root is the only one that can do this I don't see any problem. It is nice to get a warning if you do it by accident, but I hate arbitrary restrictions on root.
