I guess what you can do in golang that would be very similar to the rust impl would be this (and could be helpful even in real life, if all you need is a whole lot of timers):

  func test2(count int) {
  
   timers := make([]*time.Timer,count)
   for idx, _ := range timers {
    timers[idx] = time.NewTimer(10 * time.Second)
   }
   for idx, _ := range timers {
    <-timers[idx].C
   }
  }

This yields to 263552 Maximum resident set size (kbytes) according to /usr/bin/time -v

I'm not sure if I missed it, but I don't see the benchmark specify how the memory was measured, so I assumed the time -v.
