Module In_thread.Helper_thread

module Helper_thread: sig .. end

type t 
A Helper_thread is a thread that is dedicated to handling computations external to Async. We need them because some libraries (e.g. Sqlite3) require that certain collections of computations run in the same thread.
val create : ?priority:In_thread.Priority.t ->
?name:string -> unit -> t Core.Std.Or_error.t
create ?name () creates a new helper thread. The name will be used as the thread name for any work that that is done by the thread that doesn't get its own name.
