[Wesley Terpstra]

Here is a test program that can show the resolution of the gettimeofday and setitimer implementation:

val time = ref (Time.now ())
fun delta () = 
   let
      val now = Time.now ()
      val off = Time.- (now, !time)
      val () = print ("Delta: " ^ LargeInt.toString (Time.toMicroseconds off) ^ "us\n")
   in
      time := now
   end

val x = Time.fromMilliseconds 1
val () = MLton.Signal.setHandler (MLton.Itimer.signal MLton.Itimer.Real,
                                  MLton.Signal.Handler.simple delta)
val () = MLton.Itimer.set (MLton.Itimer.Real, { interval = x, value = x })

fun loop () = loop ()
val () = loop ()
