For linuxthreads, yes. Linux threads implements threads as
pseudo processes using rfork().
The 70MB memory usage is probably shared between all the "processes".
Unfortunately, top doesn't do a job of showing how much of processes
memory is shared with another process. Almost all forked processes share
some memory space of the parent, whether rfork() or regular fork().
