Some of this is just a general design principle, nothing specific to 
registration.  Once a VoIP platform gets to be big enough, a lot of the 
logical elements that go into it get centralised into distinct and 
dedicated components that are federated into a delivery platform.  It's 
no longer considered a good idea at that point to have one process 
perform many different functions that have varying concurrency and 
blocking implications.
