class ThreadGroup
ThreadGroup provides a means of keeping track of a number of threads as a group.
A given Thread object can only belong to one ThreadGroup at a time; adding a thread to a new group will remove it from any previous group.
Newly created threads belong to the same group as the thread from which they were created.

def add: (Thread thread) -> self
Adds the given thread to this group, removing it from any other group to which it may have previously been a member.
puts "Initial group is #{ThreadGroup::Default.list}" tg = ThreadGroup.new t1 = Thread.new { sleep } t2 = Thread.new { sleep } puts "t1 is #{t1}" puts "t2 is #{t2}" tg.add(t1) puts "Initial group now #{ThreadGroup::Default.list}" puts "tg group now #{tg.list}"
This will produce:
Initial group is #<Thread:0x401bdf4c> t1 is #<Thread:0x401b3c90> t2 is #<Thread:0x401b3c18> Initial group now #<Thread:0x401b3c18>#<Thread:0x401bdf4c> tg group now #<Thread:0x401b3c90>

def enclose: () -> self
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
