All builtins that consume events from perf's ring buffer now end up calling perf_evlist__mmap_consume(), which will allow unmapping the ring buffer when all the fds gets closed and all events in the buffer consumed. This is in preparation for the patchkit that will notice POLLHUP on perf events file descriptors.
