Sleeping and timing

val sleep : Mtime.Span.t -> Mtime.Span.t

sleep dur sleeps for duration dur and returns the duration slept. The latter may be smaller than dur if the call was interrupted by a signal. This becomes imprecise if dur is greater than ~104 days.

val relax : unit -> unit

relax sleeps for a very small duration. Can be used for relaxed busy waiting.

module Cpu : sig ... end

CPU time and information.

module Mtime : sig ... end

Monotonic time clock and sleep.

val exn_don't_catch : exn -> bool

exn_don't_cath exn is true iff exn is Stack_overflow, Out_of_memory or Sys.Break.

FIXME find a place for that.
