# ThreadGroup.enclose (from ruby core) --- thgrp.enclose -> thgrp --- Prevents threads from being added to or removed from the receiving ThreadGroup. New threads can still be started in an enclosed ThreadGroup. ThreadGroup::Default.enclose #=> #<ThreadGroup:0x4029d914> thr = Thread.new { Thread.stop } #=> #<Thread:0x402a7210 sleep> tg = ThreadGroup.new #=> #<ThreadGroup:0x402752d4> tg.add thr #=> ThreadError: can't move from the enclosed thread group
