(* As of OCaml 4.01.0 input_value and input do not quite work well * with threads. The symptom is the following. Two threads, each * of them blocked on a read (on different channels). One is not * woken up even if data is available. When the other one gets data * then the stuck one is eventually unblocked too. Unix.select with
* an unbounded wait has the same problem. *)
(* Use only the following functions on the channel *) type thread_ic val prepare_in_channel_for_thread_friendly_io : in_channel -> thread_ic
val thread_friendly_input_value : thread_ic -> 'a val thread_friendly_read :
thread_ic -> Bytes.t -> off:int -> len:int -> int val thread_friendly_really_read :

(* Wrapper around Thread.create that blocks signals such as Sys.sigalrm (used
* for Timeout *) val create : ('a -> 'b) -> 'a -> Thread.t
