A pool of systhreads, to avoid the overhead of creating a new thread for each operation.

Sourcetype t

Sourceval create : sleep_q:Eio_utils.Zzz.t -> t

create ~sleep_q is a new thread pool.

sleep_q is used to register a clean-up task to finish idle threads.

Sourceval run : t -> (unit -> 'a) -> 'a

run t fn runs fn () and then marks t as closed, releasing all idle threads.

val submit : 
  t ->
  ctx:Eio.Private.Fiber_context.t ->
  enqueue:(('a, Eio.Exn.with_bt) result -> unit) ->
  (unit -> 'a) ->
  unit

submit t ~ctx ~enqueue fn starts running fn in a sys-thread, which uses enqueue to return the result.

If ctx is already cancelled then the error is passed to enqueue immediately. Systhreads do not respond to cancellation once running.
