Hmm.

I have pulled this, but this change makes me a bit nervous.

I have this dim memory of us having deadlocks in module loading
because module loading triggered other modules to be loaded, and we
had circular dependencies..

This is from years and years ago (that whole state check is not
recent), so my memory may simply be wrong, but I thought I'd mention
it...

Interesting.  I'll try to search around to see if I can find the thread.
