I understand the preference from an esthetics point of view. From a
quantitative performance point of view, in an environment where you want
to minimize the activity that is running on a lightweight cluster node, it
has been shown that 1 is better than 2.

So, all other things being equal, if we can have 1 daemon with TCP sockets 
instead of a daemon with unix domain sockets and a daemon that turns that 
into TCP sockets, on a reasonably large cluster (1024 or more nodes) 
you're much better off with 1 daemon. 1024 node clusters are not uncommon 
these days.

Again, this is not an issue of esthetics, it's an issue of measured 
performance.
