[erlang-patches] fix a race condition when there're several applications in apps directory

[Manuel A. Rubio "Bombadil"]

Hello,

When use rebar with "apps" directory and enable cover for eunit or 
common_test, the change between apps has a race condition because the 
ETS is not killed when the new cover start (is a race condition but in 
several projects that I have it happends a lot of times).


     git fetch git://github.com/bosqueviejo/otp.git cover-fix
