Use clone() then, it's cheaper ;-)
Anyway, Linux at least *does* have unlink-on-exit unix sockets: use
the abstract unix namespace.
Enumeration is a different problem from being able to connect to an
instance, and there are several approaches to enumerating multiple
running instances.
One of the most well known at the moment is mDNS service discovery,
and each instance registering with freedesktop's Avahi enumeration
service.
