Wait! You didn't ask the first question! Oh well. If you're worried
about the difference between the description and the action, I've
deleted the description. The race condition has (probably) gone away
in 1.4 due to the addition of the --settings-startup-pause flag to
opensrf-perl.pl; that descriptive text was a hangover from 1.2 days.

Short version: Perl services start; C services start; C services
depend on Perl services (settings server in particular); Perl services
aren't ready by the time the C services ping them; C services fail to
initialize; unhappiness.
