   They are not actually processes, but threads. Linux implementation of
threads is an uncomplete fork (the clone syscall), which creates another
PCB but doesn't dissociate virtual memory and resources. That is the
reason you see a lot of "processes" (look carefully to the their
statistics, and note they are the same...).
