some manual (unnecessery) free for good manner

Browse source 
its not needed because OS is responsible to cleanup
mem allocated by terminating process, but its still
a good manner to explicitly free everything that gets
allocated...
yes this is "noise" if it terminates but neither does
harm to feel being responsible to clean up everything
ourselves. :)

at least valgrind is silently happy :P :D
