Yes, but (a) the loading program doesn't and (b) that's an
implementation
choice, not a necessity.

I talked to Don about this and you're right, that doesn't happen.
However
he also confirmed that it does load modules a second time if they are
in the main program as well as the plugin, and it would be difficult to
merge
the static and dynamic versions of the module.
