Oh, right ... yeah, it happens whenever there's a source file with the 
same name as the ASDF system (I'm using BUILD-OP), not related to how 
many lisp files there are at all.

If I set si::*init-function-prefix* before I call build-op, it doesn't 
seem to help:

"FOO"

"FOO"

Would a good solution be to always put a suffix like "_lib" on the 
aggregate init functions in the temporary object file? It seems like 
that would eliminate many of these collisions.
