A way to start all children at once?

The reason that is a bad idea is called the "thundering herd problem". 
All your child processes grab messages together. Then they all virus 
scan together. They they all expand the attachments together. Then they 
all do DNS lookups together. You get the idea.

The result is that at one moment every child needs your CPU. Then they 
all need your disk. Then they all need your network, etc. This is "A Bad 
Thing (tm)".

The staggered startups is done precisely to remove this problem. The 
delay is 11 seconds, which is perfect as you don't even get children 
started on the same number of seconds from one minute to the next.

There is (virtually always) method in my madness. :-)
