Whatever happened to semaphores (flags)? Seems to me that if a daemon is a 
dependency, the second-last startup thing it should do is connect to itself 
(since it may well be asynchronous); on success, it should run a flag up the 
pole (touch a file somewhere) to tell the world that it is up and ready to 
process requests. All of its dependents should wait for that flag to appear 
before they make their own services available. And later during operation, 
removal of the flag should cause dependent daemons to withdraw their services.
