Just to make myself clear - I clearly said in my first reply to your
post:
"One can argue whether this should result in an error message or
whether the semantics of require are satisfied if the namespaces
are loaded once each."
So I would be glad if the bug is fixed by silently stopping the load if
the namespace is already found in *loaded-libs*. After all the
infrastructure is in place and all that is needed is recording the lib
before the actual load in *loaded-libs* and if the load fails to remove
it again which slightly complicates load-one and/or load-all but still
it seems to be a small price to pay for correctness.
