No.  Threads are entities in the process, so it does not maintain
"child" processes.  Child processes are children of the parent
"processes" not threads.

If you want to kill child processes when the thread is down,

  th = Thread.new{
     Thread.current[:children] = []
     begin
       ... add child processes to Thread.current[:children]
     ensure
       Process.kill("TERM", *Thread.current[:children])
     end
  }

is the way to go.
