Change the yield in your MainReaper thread to: 

sleep 1 until ($DoneFlag || $Timeout);

[download]

Yield just relinguishes the rest of the threads timeslice. It immediately becomes eligible for rescheduling. That means that if no other thread is available to run, you've coded a very tight loop that will happily consume as much cpu as is available. By using a sleep, you will avoid thrashing the cpu. If you need finer than 1 second resolution, use Time::HiRes::sleep or the 4-arg select.

Note: This is based upon my observations of what happens on Win32. Your OS may work differently.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
