Are unreachable threads garbage collected?

>From Reppy's paper, an implementation of buffered channels translated to OCaml.
Note the internal thread to manage the state. If the buffered channel becomes
unreachable, will this thread be garbage collected?

module Buffered_channel = struct
  open Event
  type 'a t = 'a channel * 'a channel
  let make () =
    let i = new_channel () in
    let o = new_channel () in
    let rec loop = function
      | [], [] -> loop ([sync (receive i)], [])
      | (a :: aa) as aaa, bbb -> select [
	  wrap (receive i) (fun x -> loop (aaa, x :: bbb));
	  wrap (send o a) (fun () -> loop (aa, bbb))
	]
      | [], bbb -> loop (List.rev bbb, [])
    in ignore (Thread.create loop ([], [])); (i, o)
  let send (i, _) x = Event.send i x
  let receive (_, o) = Event.receive o
end
