module shows up multiple times on the search path

[tyner]

Error description

Say I have a module called "foo/bar". From the global environment, if I import it twice via:

box::use(foo/bar[...])
box::use(foo/bar[...])

then there are now two entries on the search path called mod:foo/bar. This happens regardless of whether I put a box::purge_cache() in between.

Perhaps this is not a bug, but shall we say an infelicity? Could there be an option to prevent duplication on the search path, or at least alert the user?
