Er, mistake here. That's actually once per standard_initdb, except
that all the tests I have included in my patch run it just once to
create a master node. It seems that it would be wiser to set one
socket dir per node then, remove the port assignment stuff, and use
tempdir_short as a key to define a node as well as in the connection
string to this node. I'll update the patch later today...
