Ian Downes commented on MESOS-1660:
-----------------------------------

I've done some testing on Linux and will have a patch out today that 
dynamically changes the reap interval based on number of pids monitored.

I saw much lower utilization for my test code which called kill(0, pid) and 
waitpid(pid, &status, WNOHANG) in a loop.

> Lower ReaperProcess::wait() delay to 500ms or 250ms
> ---------------------------------------------------
